Removed the scalefactor from the DRC-CIF rule parsing, so that rules 

are interpreted in the dimensions used in the cifoutput section rather
than always in centimicrons (otherwise, rules at, say, 5nm cannot be
represented in the DRC section).

* Side effects:
* Updates the DRC technology variables.
*
* Notes: "centidistance" is by default in centimicrons, but it is really in
* whatever units are declared in the cifoutput section; so if cifoutput
* declares nanometers, then units are in nanometers. This may be in
* different units from the non-CIF part of the DRC section. The escape
* sequence substitution in the "Why" text will make sure that the correct
* physical dimensions are presented to the end user.
