Feature request: Custom repeat interval

[mhanuszh]

Personally, I have an bi-monthly expense, but a generic, customizable repeat interval would be great.

There could be a group of absolute values: Every x days/weeks/months/years

And a group of relatives: Every x-th day/week/month of every week/month/year
