Massive initial commit

Changes:
- All warnings removed! acording to eclipse this is an impecable codebase
- Re-encoded all the japanese in utf-8, no more broken ?'s (was in shift_jis)
- Translated the ui, with google translate. better than nothing
- Minor bugfixes
- Minor performance improvments (removed a few threads :D)
- Fixed the undocumented Connection_Host property, so the client and server
  can be on different domains

also extended the makefile, it properly packages everything into a zip similar
to the original release (pchat400_alpha.zip)
