Special technologies are technologies that have a "civ": or "notciv": requirement, i.e. they're available to one or more factions, but not all. Currently some are grouped alongside regular technologies, others are arbitrarily distibuted over the carthaginians/, hellenes/, kushites/, persians/, romans/, and successors/ subdirectories.
- moves special technologies out of those subdirectories, occassionally implementing more consistent naming;
- updates templates accordingly;
- set 'svn:mime-type' and 'svn:eol-style' for all technologies (*.json was much faster than typing the moved file names one by one).
