Add "Mount Worm Period Preset" for PPEC

[deix]

Hi,

There is a lot of data on the Github Wiki page, that not so many PHD2 user are aware of. I see a value in adding the "pop-up" menu in the PPEC algorithm page, where the user could then pick his / her mount from the list and then the propper worm period data would be used in the PHD2:

Additionally, link to https://github.com/OpenPHDGuiding/phd2/wiki/Mount-Worm-Period-Info on Github Wiki page would be beneficial to place in the GUI - the user could then be pointed directly to the place, where he / she could add / update the data for the corresponding mount.

Probably not sustainable.
