Out of memory not caught be general exception handler

see: http://stackoverflow.com/questions/16184812/out-of-memory-exception-not-caught
Added a catch for out of memory.
Doesn't "fix" the out of memory problem, but means a less fatal crash.
tweek the image scaling code to fall inline with the android dev website to try and combat out of memory.

already added a catch for OOM error as per: http://stackoverflow.com/questions/16184812/out-of-memory-exception-not-caught
Extra checking that the retweet was a success & updating the correct cache

fixes #138 & #140
