Distorted Android

Minor

Improvements for the new Border effect. Now works, but covers the object - to be corrected.

New postprocess effect 'Border' (not working yet) and adding it to the testing app 'Triblur'.

Mesh creation: finished.

Move destroying most of statics from onDestroy() earlier, to onPause().

Reason: doing this in onDestroy() is too late, because when we have two activities, and switch between them, first the ending's Activity onPause() is called, then the starting Activity's onResume, then it's onSurfaceCreated(), then we insert all the effects, and only then the ending Activity onDestroy() gets fired off - and this might destroy the already enabled effects, like for example the Programs of the Postprocessing effects.

Move QuatHelpeer to distorted-library

Add debugging option to DistortedEffects.

On second thought, come back to Vector. The problem: before we had the potentially blocking function 'effectFinished' inside our synchronized block.

Improve EffectMessageSender: ArrayList with explicit locking in place of a Vector.

1) add missing call to BlockController.onPause() / onResume() to the Tutorial activity
2) rearrange BlockController's error reporting to make the case where the MessageSender thread has died separate
3) in such case, resurrect the thread
4) simplify and harden the EffectMessageSender
