Moved frying support from the Debugger to the Console. Also, frying now 

occurs once per frame, as long as the backspace key is held down
(previously it happened once per keypress only). Haven't decided
whether this is an improvement or not, need more testing

Also, added missing -O2 to new Makefile.

- Save CLI session to a text file.
- Supports hex, decimal, and binary input and output almost everywhere.
(disassembly is still hex)
- (partial) Support for bank switching. Only F8 cart type works for now.
- Support for bank switching. You can see how many banks a cart has,
and switch banks. There's still more to be done here though.
- Patching ROM in-place. Currently there's no way to save the patched
ROM though.

- TIA display should be updated during step/trace, so we can see our
scanlines being drawn as it happens. The emulation core wasn't
designed with this in mind, so it'll take a lot of work
- Bankswitch support in the debugger for the remaining 20-odd cart
types. Each one has to be added individually.
- Bankswitch support in the debugger for the few remaining cart types
that aren't supported.
- Patch ROM support for a few cart types doesn't work.
Future plans (post 2.0):
- Advanced breakpoint support (e.g. Break when carry flag
changes, or break when player 0 collides with player 1,
etc). This will implemented as a scripting language for
the CLI.
- Ability to patch ROM in-place, possibly including a mini-assembler
- Possibly a mini-assembler
- Support for extra RAM in Supercharger and other cart types.
- Possibly support for recording and playing back input files, like
MAME. This isn't a debugger feature per se, but it'll make it easier
