New set of Mordor maps.

Just change the name to MDATA11.MDR and overwrite your ordinary mdata11.

I strongly recommend to start a new mordor install to test it, just to have some fun :-)
If you want to just change maps with an old mordor installation, delete MDATA8.MDR to reset your automap memory (don't worry, game will re-create this file).

Known issues:
* At the moment there are only three complete levels (I'll try to add more ASAP)
* There are no chutes - I don't know how to set them
* All teleporters are random, no fixed location teleports. If someone tells me how to set them, I'll make them.

Plans for the future:
* Obviously - re-creating all fifteen levels;
* Minor item changes (some new junk instead useless items such as Sword of the Winds or Cutlass);
* Major cursed item changes (making them at least usable in some circumstances, new names and new prices to confuse old, hardcore players);
* Total changes of laired monsters.
