gimix: added support for Flex DSK disk images, will now boot Gimix Flex 3.3.
megasys1.c: Naming convention standardization & change "US" to "North America" as per title screen - NW
peplus.c: Spelling correction - NW
k052109: add missing set_colors() (nw)
flex_dsk: added support for some double-sided disk sizes.  800kB disk images are now readable. (no whatsnew)
konami cpu: converted to use delegates. nw.
k056832: updated to use delegates and inline configs. nw.

these changes are mostly driver-level, so I think they should not conflict
with anyone else's work. the only relevant change for the device code
is the removal of altK056832_vh_start. no further work on this chip is 
planned (it requires major rework)
flex_dsk: add workaround for Gimix Flex 3.6 expecting tracks 1 and 2 to be MFM.  It will now also boot. (no whatsnew)
