Integrate Pocket Paint into Pocket Code

During the Google Summer of Code I would like to integrate Pocket Paint into Pocket code. There is quite some refactoring overhead before this can be done, as Pocket Paint currently makes use of antipatterns (e.g. Singletons) and global static variables that will become a problem when merged with Pocket Code. Some features are identical in both applications (language chooser) which can be dropped and reused .
