Remove BFBC2 and MoH media from distributed content to reduce download size (#66)

Removed the media (icons, maps, etc.) for BFBC2 and MoH from the content being distributed since the demand for these games is very low.
The old files are now stored in a "Archive" folder, allowing us to provide them as a separate download. A default placeholder-map has been added for both games to prevent crashes when clicking the map-tab.

Someone (@phogue) should have a quick look if this is okay or will instantly crash something :smile:
