Gens Rerecording 11a

MD模拟器Gens Rerecording 11a发布，这是基于官方的GENS上进行改进，加入了录像录制的功能：

新版本改进如下：
-Loading roms and such from command line no longer requires use of the -rom [or relevant] command line switches (nitsuja)
-More emulation variables properly initialized on ROM load (nitsuja)
-FrameCounter positioning now adjust so that it will not run past the right edge of the screen. (upthorn)
-Fixed automatic gmv backup bug where [movie_name].bak.gmv would become the current version and [movie_name].gmv the unmodified backup. (upthorn)
-Added desync warning when playing a movie from a savestate that has no input data saved in it whatsoever. (upthorn)
-Fixed bulletproof rerecording and desync detection compatibility with savestates from recently obsoleted gens versions. (upthorn)
