OpenBOR v3.0 Build 2195 changelog:

* If only 1 pak file exists we skip menu.
* Increased size of sectors from 4096 to 8192. This should now allows pak files with long headers to load up. (Perhaps people are using directory/file names longer than 7 characters or really deep paths?!?)
* fixed: allow select was broken for player selection.
* fixed: PSP Menu file sorting caused an exception. We should pass by reference not a pointer.
* fixed: sound_unload_sample() was being used on a per frame basis. Since we cache samples and return indexes, this allows for samples to be shared. Hence we should unload them until we exit the engine.
