EMC g92 update

Les and I have found a work around for the problem of showing no g92 work 
offsets when work offsets exist in the var file.  Recent EMCs will 
produce this error if you have the following line in your ini file.  

; Startup codes for RS-274-NGC interpreter
RS274NGC_STARTUP_CODE =	G20

The simple cure is to edit that ini line, adding the g92.3 so that it 
reads

; Startup codes for RS-274-NGC interpreter
RS274NGC_STARTUP_CODE =	G20  G92.3

With this change, those g92 values are included in the displayed offsets 
and are also active.  Once you home out your machine, they should apply 
as you intended to have them apply.

This does not apply to users of RH5.2 and rt09J.
