Wanted: MAC OSX users that can confirm that this patch works well.

This patch basically makes darcs using ~/.cache/darcs/ instead of
~/.darcs/cache. Unless $XDG_CACHE_HOME is set, in which case it
will use $XDG_CACHE_HOME/darcs/.

If $XDG_CACHE_HOME is set but does not exist, or if it
is not set and ~/.cache does not exist, the missing directory
is created with permissions 0700.

Under for Mac OSX, this patch makes darcs use the directory
~/Library/Caches/, which is the current norm.

The behaviour under Windows is not modified, there does not seem
to be any norm for caches.

This amended version used System.Info( os ) instead of CPP flags,
hence does not touch darcs.cabal.

I've looked over the patch, and the code looks good. I can't test for
OSX though.

Accepted by owst http://irclog.perlgeek.de/darcs/2013-07-19#i_7345510 by
will wait a little to push them to reviewed, to ask for Mac OSX testers.

Eric confirmed on the mailing list that it worked on OSX.
