Fix instance check in getShortMapper.mapper

Needs to check for both integral types, otherwise:

	modName,object = fid

Will raise an exception, since integral types can't be iterated,
unlike tuples (which is what fid needs to be here).
Add HAIR to types converted to long fids by RacePatcher

This also fixes issue #95.
Clear RacePatcher.races_data before building patches

Otherwise, when building a patch twice without restarting, races_data
finds itself with fids in short format from the previous build(s),
when fids are expected to be in long format, which causes Bash to choke.

Closes #95
