Regeneration Rooms
------------------

Mana_Regen, Hit_Regen and Move_Regen rooms all have a limited number of die
rolls that are allowable.  They are as follows:

1d1, 1d2, 1d3, 1d4, 2d2, 1d5, 1d6, 2d3, 1d7, 1d8 and 2d4.

For Clan regen rooms, the base stat is 1d4.  For every step up the above
scale, a fee of 1 million domars is payable from the clan BEFORE the change
is implemented.
