Added PoC-alarm limit in Windows UI

Warning: The limiting-logic is little more than a PoC currently. Should
be "professionalized" within the next few commits =)
Merge remote-tracking branch 'origin/master' into WindowsUILimitAlarms
Removed TODO

Reason: More advanced handling would require a cache of some sort.
Solution: Set a limit to "OFP.LimitAmount" which takes care of
unnecessary load on its own.
