Improve Task Recurrence Options

When scheduling tasks for the future, there are currently six options for frequency: Once, Hourly, Daily, Weekly, Every Two Weeks, and Every Four Weeks.

In the enterprise setting, I'd like to see other frequency options such as Monthly (same date every month), and "Xth Of The Month" (ex: 2nd Wednesday of the Month).

Basically, if I can schedule an Outlook meeting with a certain recurrence, I should be able to schedule a task with the same recurrence.

This will improve the ability for people to schedule regular patching windows with the new pe_patch functionality (which is my use case).
