make it easy to handle syntactic sugar. In summary, compile now calls
parse(sugar('gitolite.conf')).
Details:
- cleanup_conf_line went from subar.pm to common.pm
- explode() and minions went from conf.pm to the new explode.pm
- the callback went away; everyone just passes whole arrays around now
- the new sugar() takes a filename and returns a listref
- all sugar scripts take and return a listref
- the first "built-in" sugar is written (setting gitweb.owner and
gitweb.description)
the new RC file format (of being a hash called %rc) is getting a nice
workout :-)
