bug: Bug: Ionic-1.0.0-beta14 - Parse error for lines with $attr.class on Android 2.3

[revie]

Type: bug

Platform: android 2.x webview

Running the latest Beta 14, I ran into the following error when running on Android 2.3:

D/CordovaLog( 349): file:///android_asset/www/lib/ionic/js/ionic.bundle.js: Line 46718 : SyntaxError: Parse error
E/Web Console( 349): SyntaxError: Parse error at file:///android_asset/www/lib/ionic/js/ionic.bundle.js:46718

which appears to be this line:

var headerBarEle = jqLite('<ion-header-bar>').addClass($attrs.class).attr('align-title', alignTitle);

and first reported by akhil in the Forum at:

Apparently, older versions of Android don't like "$attrs.class", as first identified last year:

#1228

Changing "$attrs.class" to "$attrs['class']" in the Ionic bundle seems to have fixed the problem for me, with no side effects in the other versions of Android and iOS I'm testing in. Should this same change be integrated back into the source tree for others who may be experiencing the same problems?
