[v1.4] Minimap script giveaway

[Chrissi]

Load the map, then remove all the contents from htdocs/graphic/continent and then reload the map and baam, there's no conmap!

That supposedly shouldn't happen. The conmap-code actually tests whether the file exists, and if not, it'll regenerate a continental map.

But, Molt and blner are right anyway: The continental map is indeed cached in htdocs/graphic/continent.
