Subject: [PATCH] Added -break command line option. It sets a breakpoint before
 emulation even starts, so you can enter the debugger before the first frame
 is even drawn. This will be useful for everyone, but I particularly need it
 for testing per-scanline TIA update code (which doesn't even exist yet).

I should eventually be able to run "stella -break kernel poker.bin" and
then advance one scanline at a time, watching the first frame get drawn.
Not even close yet :)
