Warlordocracy Early v4.2

HEY! I managed to release version 4.20 on 4/20, the day famous for the start of the Spanish-American war and the discovery of radium chloride. Much better performance and more random map generator functions.

Complete list of fixes:

-Greatly improved performance with multiple party members moving.
-Fixed bug where contracts wouldn't work if you had a full party (now able to recruit 20 additional henchmen).
-Fixed bug where explosions would cause mobiles to attack random objects if object disappears in script.
-Added river and more road options to mapRandom command (no bridges yet).
-Now forbidden to have more than 20 henchmen per map.
