fix(ngModel): do not dirty the input on $commitViewValue if nothing was changed

Calling `$commitViewValue` was was dirtying the input, even if no update to the view
value was made.
For example, `updateOn` triggers and form submit may call `$commitViewValue` even
if the the view value had not changed.

revert: fix($compile): pass transcludeFn down to nested transclude directives

This change introduced regressions for several scenarios.

feat($interpolate): escaped interpolation expressions

This CL enables interpolation expressions to be escaped, by prefixing each character of their
start/end markers with a REVERSE SOLIDUS U+005C, and to render the escaped expression as a
regular interpolation expression.

Example:

`<span ng-init="foo='Hello'">{{foo}}, \\{\\{World!\\}\\}</span>` would be rendered as:
`<span ng-init="foo='Hello'">Hello, {{World!}}</span>`

This will also work with custom interpolation markers, for example:

     module.
       config(function($interpolateProvider) {
         $interpolateProvider.startSymbol('\\\\');
         $interpolateProvider.endSymbol('//');
       }).
       run(function($interpolate) {
         // Will alert with "hello\\bar//":
         alert($interpolate('\\\\foo//\\\\\\\\bar\\/\\/')({foo: "hello", bar: "world"}));
       });

This change effectively only changes the rendering of these escaped markers, because they are
not context-aware, and are incapable of preventing nested expressions within those escaped
markers from being evaluated.

Therefore, backends are encouraged to ensure that when escaping expressions for security
reasons, every single instance of a start or end marker have each of its characters prefixed
with a backslash (REVERSE SOLIDUS, U+005C)

docs($interpolate): replace `jerk` with something nicer/more neutral

I thought `jerk` illustrated the "defacing" factor nicely, but I suppose it's not very nice to have
in official documentation.
docs(*): fix its vs it's typos.

Only use the apostrophe if you can expand "it's" to "it is" and
still have a grammatical phrase.

Closes #7524
fix(Scope): $broadcast and $emit should set event.currentScope to null

When a event is finished propagating through Scope hierarchy the event's `currentScope` property
should be reset to `null` to avoid accidental use of this property in asynchronous event handlers.

In the previous code, the event's property would contain a reference to the last Scope instance that
was visited during the traversal, which is unlikely what the code trying to grab scope reference expects.

BREAKING CHANGE: $broadcast and $emit will now reset the `currentScope` property of the event to
null once the event finished propagating. If any code depends on asynchronously accessing thei
`currentScope` property, it should be migrated to use `targetScope` instead. All of these cases
should be considered programming bugs.
