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>

If you bind using '=' to a non-existant parent property, the compiler
will throw a NON_ASSIGNABLE_MODEL_EXPRESSION exception, which is right
because the model doesn't exist.
This enhancement allow to specify that a binding is optional so it
won't complain if the parent property is not defined. In order to mantain
backward compability, the new behaviour must be specified using '=?' instead
of '='. The local property will be undefined is these cases.

we now have two types of namespaces:
- true namespace: angular.* - used for all global apis
- virtual namespace: ng.*, ngMock.*, ... - used for all DI modules
the virual namespaces have services under the second namespace level (e.g. ng.)
and filters and directives prefixed with filter: and directive: respectively
(e.g. ng.filter:orderBy, ng.directive:ngRepeat)
this simplifies urls and makes them a lot shorter while still avoiding name collisions
Changed the isolate scope binding options to:
- @attr - attribute binding (including interpolation)
- =model - by-directional model binding
- &expr - expression execution binding
This change simplifies the terminology as well as
number of choices available to the developer. It
also supports local name aliasing from the parent.
BREAKING CHANGE: isolate scope bindings definition has changed and
the inject option for the directive controller injection was removed.
To migrate the code follow the example below:
Before:
scope: {
myAttr: 'attribute',
myBind: 'bind',
myExpression: 'expression',
myEval: 'evaluate',
myAccessor: 'accessor'
}
After:
scope: {
myAttr: '@',
myBind: '@',
myExpression: '&',
// myEval - usually not useful, but in cases where the expression is assignable, you can use '='
myAccessor: '=' // in directive's template change myAccessor() to myAccessor
}
The removed `inject` wasn't generaly useful for directives so there should be no code using it.
