Release 0.1.0 is a major rewrite of the refreshd package.

Highlights:

* communication switched to UNIX domain sockets. It uses abstract UNIX 
  socket names if possible.
* improved error handling mechanism
* thread safety (I think I have eliminated the race conditions from
  refreshd_cnt library).
* better integration with r2llib. refreshd is now mature enough to stop
  peeking under skirts ;-)
* a better scavenging scheme which should eliminate the scavenger problems
  from the previous versions.
