Custom XML:s for maps [SUGGESTION]

Concise description:
Specifics:
This will improve the following aspects of the site:
- Custom XML:s for some old maps (or why not new ones), so that you could play the same map with 2-3 different sets of rules.
Specifics:
- For example, you could have classic map, but add an objective, hold asia + europe to win. Or you could have World 2.1 World Conquest, where everyone starts at starting positions and the rest of the map is neutrals. The options are unlimited.
The maps with custom XML:s would be marked with a symbol or something in the map list, and when you select the map, you'd get another choice - standard XML or one of the custom ones.
This will improve the following aspects of the site:
- I think this could bring great fun to tournaments, and give a boost to some old maps which everyone has played ad nauseum, by introducing fresh gameplay.
- Fun!
