Closes #4222
docs(guide/$location): fix broken example demo

The demo of the hash-bang vs html5-mode deep links was broken since the introduction
of a check for previously bootstrapped elements. See this commit: 3ee744cc63

We fix this problem by applying a null for the injector value of the element of the
at the root of the sub-app.
It also turns out that it was not necessary, and if fact broke the demo, to replace
the $document service for the sub-app.  This was because the $compile service calls
`$document.createElement()`, which doesn't exist on a `div`.
Finally, the bootstrap CSS was limiting the width of the ngAddress bar input box,
which made it difficult to see the changing URLs.

docs(angular.bind): clarify that bind is partial application

The `angular.bind` function reflects the definition of "partial application", which
reduces a function's arity rather than transforming a function with n args into a
chain of n functions, each having a single arg.

curry : f(x,y,z) -> f(x)(y)(z)
partial application : f(x,y,z) -> f(x)(y,z)

Closes #4241
docs(guide/directive): clarify use of binding to scopes

The use of 'angular' as sample text is confusing to the newbie in that they are forced
to confirm that the text 'angular' is not a keyword or otherwise referring to a system
component. This is changed to a more obvious sample text.

The most common form of `ngBind` is moved to the top of the list.

Closes #4237
fix($compile): don't terminate compilation for regular transclusion directives

Previously we would stop the compilation for both regular and element
transclusion directives which was wrong. Only element transclusion directives
should be terminal.
fix($compile): fix (reverse) directive postLink fn execution order

previously the compile/link fns executed in this order controlled via priority:

- CompilePriorityHigh, CompilePriorityMedium, CompilePriorityLow
- PreLinkPriorityHigh, PreLinkPriorityMedium, PreLinkPriorityLow
- link children
- PostLinkPriorityHigh, PostLinkPriorityMedium, PostLinkPriorityLow

This was changed to:

- CompilePriorityHigh, CompilePriorityMedium, CompilePriorityLow
- PreLinkPriorityHigh, PreLinkPriorityMedium, PreLinkPriorityLow
- link children
- PostLinkPriorityLow, PostLinkPriorityMedium , PostLinkPriorityHigh

Using this order the child transclusion directive that gets replaced
onto the current element get executed correctly (see issue #3558),
and more generally, the order of execution of post linking function
makes more sense. The incorrect order was an oversight that has
gone unnoticed for many suns and moons.

(FYI: postLink functions are the default linking functions)

BREAKING CHANGE: the order of postLink fn is now mirror opposite of
the order in which corresponding preLinking and compile functions
execute.

Very few directives in practice rely on order of postLinking function
(unlike on the order of compile functions), so in the rare case
of this change affecting an existing directive, it might be necessary
to convert it to a preLinking function or give it negative priority
(look at the diff of this commit to see how an internal attribute
interpolation directive was adjusted).

Closes #3558
fix(routeProvider): parametrized routes do not match against locations that would not valorize each parameters.
chore(travis): temporarily disable Firefox

I can't get it allocated on SauceLabs and so this is failing all the builds, making our Travis build useless.

I contacted folks from SL. Once we figure it out, I will revert this change.
chore(docs): fix broken IE8 test due to sanitization bug
chore($parse): convert parser() and lex() to prototype-based code

This reduces memory consumption of parsed angular expressions and
speeds up parsing.

This JSPerf case demonstrates the performance boost:
http://jsperf.com/closure-vs-prototype-ngparser

Chrome: 1.5–2x boost
FF: slightly slower (I would love to know why)
IE: 4x boost

To be clear, this doesn't have any impact on runtime performance
of expressions as demostrated in this JSPerf:

Closes #3681
fix(ngResource): Remove request body from $delete

Prevent the  obj.$delete instance method from sending the resource as the request body.  This commit uses the existing hasBody boolean to only set httpConfig.data for methods which should have a request body.

Closes #4280
style(angularSpec): add missing semicolon
style(injectorSpec): add semicolons & test helpers
style(select): fix semicolons and vars
fix(*): protect calls to hasOwnProperty in public API

Objects received from outside AngularJS may have had their `hasOwnProperty`
method overridden with something else. In cases where we can do this without
incurring a performance penalty we call directly on Object.prototype.hasOwnProperty
to ensure that we use the correct method.

Also, we have some internal hash objects, where the keys for the map are provided
from outside AngularJS. In such cases we either prevent `hasOwnProperty` from
being used as a key or provide some other way of preventing our objects from
having their `hasOwnProperty` overridden.

BREAKING CHANGE: Inputs with name equal to "hasOwnProperty" are not allowed inside
form or ngForm directives.

Before, inputs whose name was "hasOwnProperty" were quietly ignored and not added
to the scope.  Now a badname exception is thrown.

Using "hasOwnProperty" for an input name would be very unusual and bad practice.
Either do not include such an input in a `form` or `ngForm` directive or change
the name of the input.
