LOOM-TextEditorImprovements: See PR comments

Fixes numerous IME text entry and focus issues on Android and IOS, disables autocomplete, adds a smooth Y scroll to stage if (and only if)  text entry box is obscured 

This should be further tested before landing.  i have run it on Android 4.2/2.3 Nexus 7/Droid2 and iOS6 on iPad2

The feathers example features the panning.  Panning is now unnecessary on A**c**e as the auto suggest on password is gone and the layout on my devices doesn't get obscured by text entry.

Please note that I changed the java source to use spaces while leaving the Feathers on tabs, though it also had some spaces in it (as it is in the repo)
