Fix the bug where the tiles on the RHS may be marked dirty and accumulate garbage if the player dies on the RHS. Add some more debug for the crashing bug I am chasing. It looks like more than 12 segments have been added so I am adding debug to detect when the number of segments exceeds 12.

Fix problem on real HW where the player will start the next level shooting if they died while shooting, regardless of the state of the mouse. It now ignores the first poll of the mouse at the start of a level to avoid stale poll information. Add some debug in the code for jumping to the head and body segment draw routines to confirm that the table offsets are sane. I have seen a crash which indicates that sometimes the offset is incorrect.

Fix a long standing bug I have ignored for too long. When adding centipede segments on the left or right, if there was a mushroom right where the segment was arriving, it would try to change direction even though it was still mostly off-screen. This lead to some very strange segment tracks that should never happen. I have added code to ignore blocking mushrooms and not change direction when the segment is partially off-screen.

Add the ability to use mame as the GS emulator. The mouse works better under mame than GSPlus for this game. For now, I have both options in the launchEmulator script with one of them commented out. It would be good to put this into the base Makefile infrastructure so mame could be selected as the emulator to use.

Fix a crash that would happen if the last centipede segment collided with the player. Both level and player code was trying to start the next level and the corrupted things badly. Now, the level code is always responsible for starting the next level. The player code only restarts a level when the player dies and doesn't finish the level.

This build has the player moving in X and Y directions and with cleaner handling of the dirty tile to remove the inefficiencies. The good news is that there is no longer any performance problem at 2.8 MHz now that the inefficient dirty tile handling has been removed. The bad news is that they player leaves garbage behind indicating some kind of problem with dirty tile marking. But it is close.

Replace the C code which built tables at game launch time with a script which generates these tables at build time. This reduces the start time of the application and saves code space and is a necessary step before adding some new tables to handle the mouse efficiently.
