[OpenBIOS] PATCH: Minor debugger patch

[Mark Cave-Ayland]

Hi all,

This patch corrects a couple of (minor) bugs in the Forth source 
debugger; firstly the number of wordlists is held in #order, rather than 
#vocs which is the total number of wordlists which can be held 
simultaneously.

Secondly, the initial interruptforth setting in kernel/bootstrap.c is 
actually wrong, but since this is reset by enterforth() it is not needed 
anyway. Hence this line can simply be removed.

ATB,

Mark.
