Let the Companion Display Assets.

Arrange to fetch assets from the APK file in the Companion so it can
have a UI with images etc. Add a function to the PhoneStatus block
used to declare that the UI is loaded and assets should now be loaded
from the SD Card (because they would be loaded by the App being
developed!).

Added support for Tweets with Images, uploaded to TwitPic.

This also requires the user to input an API key given by
registering their app with TwitPic.

SetStatus and SetStatusWithImage have been renamed to
Tweet and TweetWithImage, as 'Tweet' is effectively a
verb and more intuitive than 'SetStatus'

TweetWithImage also tweets only the text if the image
is not found or is invalid.

Updated version numbers of the twitter component.

correctly with blockly.
