[Pacemaker] DRBD MC 0.8.12 / Pacemaker GUI

[Rasto Levrinc]

Hi,

This is the next DRBD MC release 0.8.12. DRBD MC is DRBD, Pacemaker and
Virtual Manager GUI.

This is a minor release that focuses on fixing bugs and doing what is
expected, but don't worry, it's not self-aware yet.

To keep people from command line longer, there's now start/stop Heartbeat
option in host popup menus, or start/stop Corosync if this is what you have. 

To do what is right, migrating away a DRBD master/slave resource now works
so that DRBD is not stopped but stays slave.

To make more and more options available, the group attributes "collocated"
and "ordered" were added. On the other hand these options are an abomination 
according to Beekhof, and shouldn't be used, so they are hidden in the
abomination section, I mean advanced section.

You can get DRBD MC here:
