Restore the ability to have ? in identifiers, except ? itself

? in identifiers turns out to be used in the field even in non-TASM
mode. Resolve this by allowing it in an identifier still, but treat
'?' by itself the same as we would a keyword, meaning that it needs to
be separated from other identifier characters.

In other words:

	a ? b : c	; conditional expression
	a?b:c		; seg:off expression seg = a?b, off = c
