dos: fixed floppy memory bug, added xml mapping
...
fixed bug where floppy data buffer from previous session would be saved to next session's floppy buffer when cartridge loaded.
added xml parsing option for remapping dos
added FDC_RESET_STANDBY debugging output, however standby and clock functionality are not implemented yet.
added debugging output detecting whether a floppy disk image already exists for a current rom, and creates a new disk only if one doesn't exist.

improve handling of cheats to handle things other than WRAM ( closes #97 )
...
note: mirroring detection for cheats doesn't work for two addresses in
the same 64kb bank i.e. the lowest 16 bits of both addresses must still
be the same

go back to masking MMI/O addresses
...
this was causing a segfault when starting or loading a game in
"Marvelous: Mouhitotsu no Takara-jima", wherein the SA-1 would write to
$2250 with DB == $06, making MMIOAccess::write read far out of bounds

debugger: add a flag indicating that the debugger is accessing the bus; this is used to suppress unwanted side effects of reads (e.g. cothread switches, latch-on-read registers) and to allow ROM to be modified (in place of MappedRAM::write_protect(), which is going away soon)
