Warlordocracy Early v4.5

Mostly working on new baddies, swarming AI scripts, plus a bunch of little changes.

Complete list of changes:

-Added baddie sprites and scripts: shark, shambler, beetle, mycanoid, ratfolk, moonhead (not in Ch.1).

-Added new script command: "objDestLast" to set object's destination to previously-selected object (swarm AI).

-New parameter: "if_objNear=default" to check for objects with same name as current object (swarm AI).

-Changed "if_objNearMob" to avoid looking for mobiles of same name (for that use "if_objNear=default").

-Updated Player's Manual (new monsters, combat) and Builder's Manual ("mapSand", "objDestLast", more).

-Added script commands to change all map tiles: "mapBlockAll", "mapBlockVisAll", "mapBlockFlyAll".

-Clamp trap script now makes sound, increased damage from 12 to 20, caltrops from 4 to 6.

-AI now has a chance to attack hostile mobiles that it collides with.

-Sand tiles now slow down movement (can also be used for mud, etc.).

-Fire spreads faster, but now has max spread in scripts.

-Fixed pausing screwing up object sprite animations.

-Improved "mapRandom" generator a bit.
