Small changes in ZwiftMap (macOS and Windows)

ZwiftMap just got a few changes and is now at version 0.2.0.

Mac only: There is a new menu item which does the same as the magic key combo. It toggles whether the
map window responds to mouse events or not.

Besides that I changed the method to find the Zwift log file. This hopefully
makes the app robust to situations where the Documents folder has been moved to
a non default location (an issue reported by a Windows user).
