Add namespace handling in attribute values
Previously, you could only reference namespace prefixes in attribute names:
<View xmlns:appcompat="http://schemas.android.com/apk/res/android.support.v7.appcompat"
appcompat:name="hey"
...
Now you can also reference them in resource names within an attribute value:
...
android:text="@appcompat:string/confirm"
...
Which will be treated as "@android.support.v7.appcompat:string/confirm".
