Drop Pino from default list for Fedora 15

[Rahul Sundaram]

Hi

As  a co-maintainer, I would note that it is not in a very usable state
and upstream is not going to fix these issues in time for the Fedora 15
release.  You can replace it with Hotot or Gwibber if it is better or if
it too late to be doing this, just not ship with a micro blogging client
at all and evaluate one of the options for the next release.   Thanks

Rahul
