Improvement of JTAC Kneeboard page

[buur]

At the moment, the Kneeboard page which show us the communication with the JTAC had the coordinates in the format MN17118326. It will be very helpful to have the full MGRS Coordinates. E.g. 38T MN 17118326.

Reason for this is that for some modules you have to recalculate the coordinates in other coordinates systems and therefore the complete coordinates help.

Also will be nice when also the remarks would be shown into the page.
