Redesign layout and general UI polish

[angrave]

Sometime ideas -
Minimize 'useless' space. i.e. Bigger editor area.
ie. Maximize fraction of screen realestate to task in hand.
Larger editor font?
Rethink button placement e.g. run button in bottom left of editor.
Currently there are too many buttons and not enough of reason to explore them.
About box could also contain level instructions and general help.
Legal info could be a copyright sentence in 8pt at base of screen and a text hyperlink.
Need a privacy policy.
Java reference link as a sticky menu item. i.e. don't need to play a game to get to reference.
Maybe animated -add captions to icons to explain their meaning?
Pop-up help first time a new level is tried. Slowly introduce button usage as more games are played.
