Fix server crasher

Initial theme selection is now random. Theme prompt now has a search input and no longer uses FlowLayout. (Resolves issue #520)

this should not be exposed

- Collect synced packets to send within 1 second (cSendEmptyPacketTime) into buffer which is flushed each second. - Send empty packet only if there was no other synced message within last second. This should reduce traffic load: less bytes and less packets (less packets is very good for the server too).

Trying to prevent audio mute from endlessly spamming. Untested.

Hedgeroid: Removed reference to obsolete libphysfsrwops.so It is now compiled as part of libphysfs.so

Merge

trying to prevent sticking. PS. code is hard to read when drunk.
