Access violation crash

[tmewett]

From tinyrodent:

Just had the game crash, first time in a while. CE 1.8.2, Windows 7 64-bit. Just before this happened, I detonated a large cloud of explosive gas - unsure if that was related.

Problem signature:

Exception code 0xc0000005 is apparently access violation/invalid memory access. The error occurs at PC 0x000000000000716e into msvcrt.dll. I don't really know how to find out what function this is in.

@tmewett This could be due to out-of-bounds errors in PowerTables.c. I was debugging with the sanitizer and got this error during some intense in-game action:

src/brogue/PowerTables.c:117:12: runtime error: index 204 out of bounds for type 'fixpt [200]'

The functions in this file are not all correctly guarded, e.g POW_REGEN[bonus] with bonus = -10 ...

@tmewett I'm working on a bunch of bugfixes, including PowerTables.c, here.

Going to assume this was the same as #221, now fixed.
