feat($compile): bind isolate scope properties to controller

It is now possible to ask the $compiler's isolate scope property machinery to bind isolate
scope properties to a controller rather than scope itself. This feature requires the use of
controllerAs, so that the controller-bound properties may still be referenced from binding
expressions in views.

The current syntax is to prefix the scope name with a '@', like so:

    scope: {
        "myData": "=someData",
        "myString": "@someInterpolation",
        "myExpr": "&someExpr"
    },
    controllerAs: "someCtrl",
    bindtoController: true

The putting of properties within the context of the controller will only occur if
controllerAs is used for an isolate scope with the `bindToController` property of the
directive definition object set to `true`.

fix(ngRepeat): make allowed aliasAs expressions more strict

Ensure that aliasAs expressions are valid simple identifiers. These are still assigned to $scope in the same way
that they were previously, however now you won't accidentally create a property named "filtered.collection".

This change additionally restricts identifiers to prevent the use of certain ECMAScript reserved words ("null",
"undefined", "this" --- should probably add "super", "try", "catch" and "finally" there too), as well as certain
properties used by $scope or ngRepeat, including $parent, $index, $even, $odd, $first, $middle, or $last.

fix(input): by default, do not trim input[type=password] values

Do not trim input[type=password] values

BREAKING CHANGE:

Previously, input[type=password] would trim values by default, and would require an explicit ng-trim="false"
to disable the trimming behaviour. After this CL, ng-trim no longer effects input[type=password], and will
never trim the password value.

feat($compile): use allOrNothing interpolation for ngAttr*

allOrNothing interpolation is now used for ng-attr-*, under all circumstances. This prevents
uninitialized attributes from being added to the DOM with invalid values which cause errors
to be shown.

BREAKING CHANGE:

Now, ng-attr-* will never add the attribute to the DOM if any of the interpolated expressions
evaluate to `undefined`.

To work around this, initialize values which are intended to be the empty string with the
empty string:

For example, given the following markup:

    <div ng-attr-style="border-radius: {{value}}{{units}}"></div>

If $scope.value is `4`, and $scope.units is undefined, the resulting markup is unchanged:

    <div ng-attr-style="border-radius: {{value}}{{units}}"></div>

However, if $scope.units is `""`, then the resulting markup is updated:

    <div ng-attr-style="border-radius: {{value}}{{units}}" style="border-radius: 4"></div>

docs(guide/module): make the use of `ng-app` explicit in example

Helpful for people new to Angular to see the ng-app declaration in context with the expression
example. This will help illustrate the "Important thing to notice" point which follows: "The
reference to myApp module in <html ng-app="myApp">. This is what bootstraps the app using your
module."

fix(input): use lowercase method to account for undefined type
fix(ngRepeat): allow aliasAs identifiers which contain but do not match reserved words

Currently if a reserved word occurs anywhere within the aliasAs identifier, we throw. This CL fixes
this behaviour by allowing these identifiers, since they are technically perfectly valid.

refactor($compile): rename `directive.type` to `directive.templateNamespace`

Also corrects the tests for MathML that use `directive.templateNamespace`.

BREAKING CHANGE (within 1.3.0-beta): `directive.type` was renamed to `directive.templateNamespace`

The property name `type` was too general.
fix($compile): use the correct namespace for transcluded svg elements

Via transclusion, svg elements can occur outside an `<svg>` container in an
Angular template but are put into an `<svg>` container through compilation
and linking.

E.g.
Given that `svg-container` is a transcluding directive with
the following template:
```
<svg ng-transclude></svg>
```

The following markup creates a `<circle>` inside of an `<svg>` element
during runtime:
```
<svg-container>
  <circle></circle>
</svg-container>
```

However, this produces non working `<circle>` elements, as svg elements
need to be created inside of an `<svg>` element.

This change detects for most cases the correct namespace of transcluded content
and recreates that content in the correct `<svg>` container
when needed during compilation. For special cases it adds an addition argument
to `$transclude` that allows to specify the future parent node of elements
that will be cloned and attached using the `cloneAttachFn`.
