Oops, forgot path

Cleaver tweaks based on feedback. Nerf damage, shrink radius. This means cleaver will embed into ground quite a bit further.

oops. more specific ammo tests. maybe could use a few more properties

Allow moving after firing cleaver. This changes multishoot behaviour quite a bit. Needs a lot of testing.

Credit links now yellow instead of blue.

Remove Structure from localisation

Implements protocol message JOINING on frontend, so client in a room always displays correct room name, even when room name changes. Fixes issue #522.

Removed in-lineedit labels such as "search:" and "room name:" due to size issues with localization and platform differences.

Fine, merge :-\

Send JOINING message in response to FOLLOW. Actual join may still fail due to room restrictions. Not tested.

Fix the checker after some testing

New checker of engine messages which is aware of glued together messages

Also convert teams to complete game config. The whole feature is still untested at all.

Fix official server build

- Handle mapgen-specific parameters - Convert ammo set into engine messages
