Filter support, Admin fixes, Init-Full change.

I Fixed all of the admin screens to include list_filter/search/display support
Also atmo-init-full was incorrectly writing the 'exit 0' commands in
/etc/rc.local, so I've removed it (and updated the hash)
Lots of changes to imaging as I
finalize migrations from CentOS+Euca --> Openstack
