Change nav-bar type attribute to accept either a string or AngularJS expression

[jough]

Right now nav-bar type="class name strings" only accept class strings, but if it accepted an Angular expression or a string we'd be able to change the classes on the nav-bar (and I suppose header-bar) by setting a $scope variable.

As discussed here:

I'll note that accepting a string will keep backwards compatibility. There are numerous AngularJS built-in directives that do this, so it would be keeping with the spirit of Angular as well.

Thanks @jough! added :-)

This doesn't seem to work? I'm binding a class name to $rootScope, and then using it like so:

$rootScope.headerClass = 'bar-positive';

<ion-nav-bar type="{{headerClass}}" class="nav-title-slide-ios7">

HTML output: (no class added)

Will this work for all attributes in ionic, like view-title attribute in <ion-view>?

@jough It looks like the type attribute was removed in place of using classes. I tried using ng-class but it doesn't seem to carry the class over to the ion-header-bar. Is there a new supported way to do this?
