Renamed/deleted files are not synchronised

[w0ng]

From @IvanUkhov's comment in #11

Let me note the following inconsistency:

CrimsonText-Roman.ttf has been renamed into CrimsonText-Regular.ttf, but you have both;
kopubbatangpro has been renamed into kopubbatang, but you have both;
the naming scheme of Raleway’s styles has been changed, and Heavy is no longer a part of the family, but you still have it.

Fixed by updating bash script to handle removed/renamed files dc678a1
