bspwm: add alwaysResetDesktops (#2785)
If set to true, desktops configured in `monitors` will be reset every time
the config is run.

If set to false, desktops will only be configured the first time the config is run.
This is useful if you want to dynamically add desktops and you don't want them
to be destroyed if you re-run `bspwmrc`.
