drop any reference of GWT annotations and Edition.GWT into the "non-GWT' source code (meaning annotations about GAE, android, etc are kept in this version of the code, and will ba handle later)
drop any *.java.gwt files from source code (meaning, that any other gae, android, specific files are kept and will be handled later)
Hi @jlouvel, after reporting 2.4 code into the 2.5 branch, I've tried to isolate the GWT edition.
The pull request is quite huge, sorry...
