add multi-day per-week repetition

[cyphar]

Currently, Calendar only supports having quite simple repetitions. You can repeat an event every X days, weeks, months or years. However, you can't do what Google Calendar does, which is to repeat an event on certain days every X weeks (for example, every second monday and tuesday). You can have events that occur every second week, but not every second week on multiple days.

This is quite important for meetings and other such things. I'd just take a page out of Google Calender's book on how the UX should look.

please test calendar-1.5.8-rc1.tar.gz

we enhanced the recurrance support quite a bit

Did some testing - it looks like repeating once a month but selecting a day of the weeks behaves as if weekly repeating was selected.

Thanks for testing!!!

Yeah but that's correct... You can see the difference if you change the interval to 2
A correct monthly repeating needs additional information we didn't implement yet (bymonth)

But you are right! We have to limit rules like this somehow
