[Engine-devel] better gwt compile times

[Gilad Chaplik]

Use draftCompile flag: Enable faster, but less-optimized, compilations.

draft compile only for gecko:
-Dgwt.userAgent=gecko1_8 -Dgwt.draftCompile=true, Total time: 2:10.928s (3:05s without it)
Saves a cool one minute (more time to be stuck in traffic)

*obviously gwt developers should test their code fully compiled (for all browsers and without drafCompile flag)

Thanks,
Gilad.
