Geocaching: fix geotools call when locale is not C

In my locale, the call was made with a comma as decimal separator.
The backend tool was unable to understand the required coordinates.

The latitude and longitude are now serialized in C locale before their
insertion in the command line.

[QA] Improve create zoom menu to use G_N_ELEMENTS to know array bounds.
Fix incorrect setting to lowest zoom value when clicking away from the statusbar zoom menu.

The only happens on the very first time since the active menu entry is not assigned and so defaults to first entry.
Unfortunately in GTK+ clicking away from the zoom menu still generates a 'selection-done' callback.
Thus ensure an active menu entry is set on initialization.
[QA] Protection from trying to use small values in the zoom combo box.
Remove shell script as route capabilities are now in Viking.
Waive copyright on my accessory scripts to build Viking on Windows.
