[OpenBIOS] Paflof with case insensitive dictionary lookups.

[Stefan Reinauer]

Hi,..

as described in one of my last mails, case insensitive number parsing
and dictionary lookups are needed for IEEE compliance. I made a little
patch to Paflof, that does this.
As Segher suggested, I created a word COMP-NOCASE, which is used by
$FIND instead of the case sensitive COMP word. It uses UPC to uppercase
the values while comparing. 
Additionally I changed DIGIT to uppercase a digit before comparing it to
A-F so deadbeef is now a valid hex value, like DEADBEEF is.
This should be checked in asap.
