Proposed fix for while end debugging info

This patch corrects the END token location and fixes the debugging line numbers
for the WHILE END loop.  The fix passes a relative token number down to
M2Quads.mod and is added to GetTokenNo (which is always one beyond the current
token processed).
This implementation should be extended to other loops and condition statements.
