* source/: alleg/sasound.c, alleg/soundcfg.c, seal/sasound.c:
sound fixes by nlx_doom : avoid calling voice_set_position too often in allegro. Now we call it only once every 10 seconds, which allows us to get rid of these annoying clicks. In seal, just call this less often too, just to use less cpu (no clicks here !).

try to fix layers order (or more specifically video chips order) in batsugun. There is still something wrong though. bg0 (key f5) should not be drawn at the boss of level2, or should be drawn below and not over the bg… Also fix the year for bbakrada !

* source/gui/about.c:
make the Game Information dialog a little wider (for the history).
