Title: Removed allowBack because this attribute is not required by library

I discovered that merging of my app AndroidManifest fails with AndroidManifest specified by library.
There is workaround to pass merge (which is broken with 0.14.1 android gradle plugin) but I think there is no sense to keep this attribute in library manifest.
