(PS3) Attempt again to 'fix' analog input - starts to somewhat

Browse Source 
'work' but still can't hold left/right of the stick in a a certain
direction ahd have the character run. PS3 analog values are 'short'
but only 0-255 is actually used. Doing u8 to s16 conversion now
but it still doesn't work alright - pressing in a certain axis will
make the character 'move' only briefly. Any help would be GREATLY appreciated
so we can finally have 'working' analog controls
