Add FreeBSD update detection to syscache.
New commands:
syscache hasupdates: [true/false] Updates available
syscache needsreboot: [true/false] Needs to reboot to finish updates
syscache updatelog: Full text output of the check for updates

This will only run the update check once every 24 hours (or whenever syscache gets restarted), while the reboot needed flag will get updated with every sync (instant check).
Update pc-systemupdatertray to use the new syscache system information (updatesavailable)
Clean up the info loggin in syscache a bit (make sure to stampt the time/date on the sync's)
Save my recent updates to pc-sysconfig (still not ready for use).
Clean up the qt4 AppCafe update messages a bit. Now it should always show the proper message.
Another couple parsing/message fixes for the Qt AppCafe during updates.
Another couple little fixes for the new usage of syscache in the pc-systemupdatertray.
