* added run mode: double tap forward key to run (1)
* improved animation load mechanism to allow using same mesh in multiple sequences: resulting in reduced load time, disk and memory usage
* seperated walk forward, backward, turn, strafe left, right and run animations
* improved footstep synchronization
* improved the way user movements sent to other clients: they are almost replicated now in an efficient way
(1) i've just noticed that run mode doesnt work on win32 platforms since Java generates different KeyEvent sequences on win32 and linux. i'll fix it soon
test tool running to show the sent user movement
