Ability to create linked custom randoms.

Proposed change: add a new binary value to the list of magic path mask list. The first mask, for Fire, is 128. If the lower ones are unused, one of them could be used to change the random into +2 levels instead of +1.

An example of use: I'd like to give EA R'lyeh Mind Lords more powerful magic via a linked random, and perhaps change few MA Atlantis descriptions to hint to an enslaved aboleth, instead of a starspawn, in the Coral Towers.
I'd like to make them S3W2 mages with a 100% random that gives them level 2 in one of W, E, S or D. This would make them S5W2, S3W4, S3W2E2 or S3W2D2 mages.
Currently, I can only give them to 100% WESD randoms, which makes them almost identical to MA R'lyeh Starspawn mages (magic-wise).
