Map grid in web view offset from ingame grid on certain maps.

[MildlyInterested]

1. Open map in TacMap, e.g. G.O.S N'Djenahoud
2. Ingame x direction starts at 1 on this map and not zero like shown in TacMap.
3. Y direction grid ingame starts at 0 slightly below the map, this can be seen in TacMap as the grid numbers don't align with the grids itself. Picture illustrates the gap between the 01 y marker and the 01 line on map.

This is probably only affecting a few maps but makes it quite difficult to find spots you've marked in the browser while making the mission in the editor (no access to Ctab there..).
