pMARS 0.9.2 Continuation Mod...

The stock pmars 0.9.2 (and 0.8.6) interpret "\" to mean continue
on the next line. Nice idea, common for many languages, however
it causes PaperOne and Marcia13 from the Wilkies test set and
Jack in the Box from the Wilmoo test set to malfunction as they
use "\" in the comments to point out code segments. The warriors
themselves can be fixed by adding a space after the offending "\"
character(s) to prevent them from being mis-interpreted but it
is more desirable to not have to modify existing code.

This modification to asm.c changes the behavior so that "\" is
treated as a continuation character only if a comment symbol is not
present on the line, thus permitting old unmodified warriors to run
correctly while preserving the ability to use "\" to continue long
lines of redcode with long labels and/or complex expressions.
