docs(guide/bootstrap): add note about ngApp and manual bootstrap
chore(grunt): add jscs task to test task

It is too easy to forget to check jscs for things like trailing whitespace
before pushing commits, such as simple doc changes.  This then breaks the
build and is messy.  Adding jscs to the test task gives people a slightly
better chance of catching these before pushing.
docs(css): ensure all type-hints have a background color

If the type of a type-hint was not recognized, say a "Promise", then
the background color was left as white.  Given that the default
foreground color is also white, this meant that such type-hints were
invisible.

fix($parse): mark constant unary minus expressions as constant

Previously, constant numbers with a unary minus sign were not treated as constants. This fix corrects
this behaviour, and may provide a small performance boost for certain applications, due to constant
watches being automatically unregistered after their first listener call.

refactor(jqLite): make HTML-parsing constructor more robust

Previously, the jqLite constructor was limited and would be unable to circumvent many of the HTML5
spec's "allowed content" policies for various nodes. This led to complicated and gross hacks around
this in the HTML compiler.

This change refactors these hacks by simplifying them, and placing them in jqLite rather than in
$compile, in order to better support these things, and simplify code.

While the new jqLite constructor is still not even close to as robust as jQuery, it should be more
than suitable enough for the needs of the framework, while adding minimal code.

docs(guide/bootstrap): remove extra call to angular.module()

There was an extra call to angular.module() not being used in 'getter' mode. While this doesn't
break the demo app, it does look kind of weird, so lets toss it.

Closes #6972
fix(Scope): more scope clean up on $destroy to minimize leaks

Due to a known V8 memory leak[1] we need to perform extra cleanup to make it easier
for GC to collect this scope object.

V8 leaks are due to strong references from optimized code (fixed in M34) and inline
caches (fix in works). Inline caches are caches that the virtual machine builds on the
fly to speed up property access for javascript objects. These caches contain strong
references to objects so under certain conditions this can create a leak.

The reason why these leaks are extra bad for Scope instances is that scopes hold on
to ton of stuff, so when a single scope leaks, it makes a ton of other stuff leak.

This change removes references to objects that might be holding other big
objects. This means that even if the destroyed scope leaks, the child scopes
should not leak because we are not explicitly holding onto them.

Additionally in  theory we should also help make the current scope eligible for GC
by changing properties of the current Scope object.

I was able to manually verify that this fixes the problem for the following
example app: http://plnkr.co/edit/FrSw6SCEVODk02Ljo8se

Given the nature of the problem I'm not 100% sure that this will work around
the V8 problem in scenarios common for Angular apps, but I guess it's better
than nothing.

This is a second attempt to enhance the cleanup, the first one failed  and was
reverted because it was too aggressive and caused problems for existing apps.
