- fixed: stats count for nodump-only clonesets in splitmerged mode counts wrong
- fixed: sets with no roms/samples/chds at all are shown in the miss list as missing
- fixed: fixdats header description/name tags hold full pathname
- misc: show stats, save auto fixdat, save fastscan only if the scan was not stopped
- misc: increased tooltip time for setinfo/rebuilderadvanced
- misc: changed batchrun's rebuilder options to radio buttons and don't disable the settings
- misc: some minor menu and diskchecksum adjustments
