SessionRestore add virtual desktop size filter!

[ewerybody]

You'd want to have the settings only applied to a certain type of screen setup, right?
So we need a combobox to select the setup via virtual desktop size you want to edit.

There is already GetVirtualScreenCoordinates() in ahklib/functions/. We'll use that as an identifyer.
this one will be prefixed to the data thats analysed by the restore function. Where there is currently:

[["procname.exe", "classname"...], ['procname2.exe', ...], ...]

it will be:

{
  "4520, 1920": [["procname.exe", "classname"...], ['procname2.exe', ...], ...],
  "1920, 1080": [[...], ...]
}
