updated gitignore
interactiveMap - Update

New structure in variant directory:
- Extra folder for interactiveMap
- Orderinterface for IAmap will be only loaded if folder exists
- Autoload-Function which automatically loads every JS-script inside
the interactiveMap-folder
- variant's extensions of interactiveMap.php (main php class for IAmap)
now located in new interactiveMap-folder (classes before)
- IA_smallmap.png (name change!) now located in new
interactiveMap-folder (resources before)
IAmap - Classic
IAmap - ClassicVS
IAmap - Modern
IAmap - WWIV
IAmap - WWIV_V6 + fix in OrderInterface

IMPORTANT: Reinstall needed
As install.php had to be modified so the coordinates of the territories
are also stored as smallmap-coordinates (only the smallmap-coordinates
are loaded for JS-scripts), the variant needs a reinstall.
Alternatively the coordinates can be copied manually in the database.
