BosWars map editor saves without extension and then doesn't open the map

[Volodya]

Binary package hint: boswars

To reproduce:
Start Boswars
Start a map editor
Save the map
in the map name enter "example"
Exit editor
Try to start the game with the map you've just saved

What happens:
The map you've saved is shown as a regular directory (which it is), not as the map.
In order to make it a map you need to remember yourself to save it with .map extension.

What i expect to happen:
Either:
1. Detect if the directory is a map, and display it as such.
2. If, when saving a game, the name doesn't end with .map, it should be automagically added (clearly it's intended).
