Use a simplistic multiply to simulate contrast control. InterPro systems write to a "virtual contrast DAC" register/latch of some kind, which presumably adjusts the reference voltage produced by the Bt438 before it enters the RAMDAC; this approximation is very crude, however it's simple and produces a satisfactory visual result.

* streamline templates in addrmap.h
* get rid of overloads on read/write member names - this will become even more important in the near future

* bt45x: new devices
Basic implementation of various Brooktree RAMDAC devices. Two of these (bt457, bt458) are used by InterPro graphics boards currently under development, the others are unused/untested at this point.
* bt45x: tweak descriptions (nw)
