Misc CXD improvements, exporting/reading fixes

Browse source 
Add XD checksum fixing/checking, now implemented
Fix XD xk3 r/w sizes. Was using colo size
Fix XD xk3 filename checksum. getCHK does checksum over 8-232, XD is too
short. just use ccitt16 for the random identification piece of both
xk3's and ck3's.
