chore(sortedHtml): print attributes with empty value

I had to also fix some tests as they started failing on IE8.

We should figure out why these extra attributes are set in IE8,
but I'm too tired of IE to worry about it now. Since I'm
not introducing this issue just making it visible, I'm going
to commit this as is.
fix($compile): compile replace directives in external template

Passing DOMNode#childNodes to compileNodes when compiling remote
template, so that directives with replace:true can be compiled.
The previous version used jqLite#contents which returned collection
that was not updated during the compilation.

Closes #1859
fix(ngMock): fix isSpecRunning to work for Mocha

When running inside Mocha, don't look in Jasmine's spec.queue.running.
It's not there. This is documented as issue #1467; I think this issue was
also responsible for #1589 and recent complaints in #1253.

Closes #1467.
docs(ngMock): remove Jasmine-only comments now that Mocha works

Remove comments about angular.mock.inject and angular.mock.module
being available for jasmine only. Since 1.1.1 the intent is that
they be available for mocha as well; now they even work!
docs(ngMock): fix minor typo in comment

Change "constroctor" to "constructor".
fix($http): don't encode URL query substring "null" to "+"

Fixes issue in encodeUriQuery used by $http and $resource that
treats null as a string and replaces the characters "null" with "+".
feat($compile): add attribute binding support via ngAttr*

Sometimes is not desirable to use interpolation on attributes because
the user agent parses them before the interpolation takes place. I.e:

<svg>
  <circle cx="{{cx}}" cy="{{cy}}" r="{{r}}"></circle>
</svg>

The snippet throws three browser errors, one for each attribute.

For some attributes, AngularJS fixes that behaviour introducing special
directives like ng-href or ng-src.

This commit is a more general solution that allows prefixing any
attribute with "ng-attr-", "ng:attr:" or "ng_attr_"  so it will
be set only when the binding is done. The prefix is then removed.

Example usage:

<svg>
  <circle ng-attr-cx="{{cx}}" ng-attr-cy="{{cy}}" ng:attr-r="{{r}}"></circle>
</svg>

Closes #1050
Closes #1925
feat($resource): ability to override url in resource actions

Resources now can defined per action url override. The url is treated
as a template rather than a literal string, so fancy interpolations
are possible.

See attached tests for example usage.
feat($route): add `caseInsensitiveMatch` option for url matching

with this property urls can be matched case-insensitively which
enables some new use cases.
feat($compile): support for dynamic template generation

`template` and `templateUrl` properties can now be optionally defined
via a function. This allows templates to be dynamically generated on
the fly.
feat($compile): allow directives to modify interpolated attributes

A directive can now set/update/remove attribute values even those containing
interpolation during the compile phase and have the new value be picked up
during the compilation.

For example in template:

<div replace-directive some-attr-or-directive="{{originalInterpolationValue}}"></div>

the replace-directive can now replace the value of some-attr-or-directive during compilation
which produces this intermitent template:

<div replace-directive some-attr-or-directive="{{replacedInterpolationValue}}"></div>

or even

<div replace-directive some-attr-or-directive="replacedStaticValue"></div>

as well as

<div replace-directive some-attr-or-directive></div>
