- started changing distant chat so that it works with GXS ids instead of PGP ids. Something is still broken in
  service control. Crypto is not done yet => distant chat is unencrypted.
- changed GUI for distant chat. Removed invitation system.
- added menu item to distant chat GXS ids from IdentityItem (only entry point for now).
- fixed bug in chat lobbies causing re-connexion of lobbies not to happen everytime (bug reported bu Lain)
