docs(guide): fix a typo
docs($scope): clarify documentation for $broadcast
fix($browser): should use first value for a cookie.

With this change, $browser.cookies()["foo"] will behave like
docCookies.getItem("foo") where docCookies is defined at
https://developer.mozilla.org/en-US/docs/DOM/document.cookie

This fixes the issue where, if there's a value for the XSRF-TOKEN cookie
value with the path /, then that value is used for all applications in
the domain even if they set path specific values for XSRF-TOKEN.

Closes #2635

feat(select): match options by expression other than object identity

Extend ng-options with a new clause, "track by [trackByExpression]", which can be used when
working with objects.  The `trackByExpression` should uniquely identify select options objects.
This solves the problem of previously having to match ng-options objects by identity.
You can now write: `ng-options="obj as obj.name for obj in objects track by obj.id"`
The "track by" expression will be used when checking for equality of objects.

Examples:
<select
    ng-model="user.favMovieStub"
    ng-options="movie as movie.name for movie in movies track by movie.id">
</select>

scope: {
  user: { name: 'Test user', favMovieStub: { id: 1, name: 'Starwars' } }
  movies: [{ id: 1, name: 'Starwars', rating: 5, ... }, { id: 13, ... }]
}

The select input will match user favMovieStub to the first movie in the movies array, and show
"Star Wars" as the selected item.
feat($resource): collapse empty suffix parameters correctly

Previously only repeated `/` delimiters were collapsed into a
single `/`.  Now, the sequence `/.` at the end of the template, i.e.
only followed by a sequence of word characters, is collapsed into a single
`.`. This makes it easier to support suffixes on resource URLs.
For example, given a resource template of `/some/path/:id.:format`, if
the `:id` is `""` but format `"json"` then the URL is now
`/some/path.json`, rather than `/some/path/.json`.

BREAKING CHANGE: A `/` followed by a `.`, in the last segment of the
URL template is now collapsed into a single `.` delimiter. For example:
`users/.json` will become `users.json`. If your server relied upon this
sequence then it will no longer work. In this case you can now escape the
`/.` sequence with `/\.`
docs($timeout): minor cleanup

Added a comma separator in the statement
Removed the word the from the statement
Used whose instead of who's in the following statement
Italicized false in the statement
Used a comma separator in the statement
feat(scenario): adds mousedown and mouseup event triggers to scenario

Added mousedown and mouseup event triggers to scenadio dsl 'element' expression.
Added mousedown and mouseup to the custom jquery trigger method to generate real events.
feat(ngSrcset): add new ngSrcset directive

In line with ngSrc and ngHref, this new directive ensures that the
`srcset` HTML5 attribute does not include a pre-interpolated string.
Without it the browser will fetch from the URL with the literal text
`{{hash}}` until AngularJS replaces the expression inside `{{hash}}`.

doc(guide): add links to angular-seed examples

The examples in the angular-seed project are better than nothing,
which is what we currently have here!
feat($http): add a default content type for PATH requests

The default header is now application/json which while not perfect
in all cases is better than the browser default application/xml.

The new headers also makes for better compatibility with Rails 4
fix($resource): null default param results in TypeError

Fixes issue when setting a default param as `null` error
`TypeError: Cannot read property 'charAt' of null`
feat($parse): add support for ternary operators to parser

Add '?' token to lexer, add ternary rule to parser at
(hopefully) proper precedence and associativity (based
on https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Operators/Operator_Precedence).
Since (exp1 && exp2 || exp3) is supported by the parser,
and (exp1 ? exp2 : exp3) works the same way, it seems
reasonable to add this minor form of control to templates
(see #719).
fix(jqLite): pass a dummy event into triggerHandler

Previously, anchor elements could not be used with triggerHandler because
triggerHandler passes null as the event, and any anchor element with an empty
href automatically calls event.preventDefault(). Instead, pass a dummy event
when using triggerHandler, similar to what full jQuery does. Modified from
PR #2379.
