Asset management; for now just images, and not really tested.
xCodea server cache will be invalidated with this update!
Ported eval capability and asset folders prefs to menuapp.
More groundwork for full asset management (will require Codea updates).
Fixed ftype header bug
Fixed run update() hook only on file changed on server
Fixed pasteboard copy source:line of error for topmost in stacktrace
Fixed remove all dependencies on server
Fixed --src=src
Merge branch 'assets' into dev
Will resume work on asset mgmt when Codea gets the required features.
