[Duel/FFA] Imprisoned

Thank you very much for the update, Justin. Now that the 100Armor is gone, I find the gameplay fairly tight and thrilling. I think your point is completely reasonable and that the change is acceptable. I'm interested to hear what experienced duelers think of it.

Here are some very minor and trivial issues I noticed.

1: The latest version of the map package contains the textures for SilentSiege which I doubt are used in this map. Please remove them, if they are not necessary.

2: Please think about setting the BGM in the mapinfo file, so that players could hear the music they like while playing locally by creating their own version of mapinfo.
