hobbit case-sensitive-ness



Hobbit changes all variable names to be lowercase.
Given that Guile has case sensitivity, I think the following
patch should be applied.  One might wish to have the opposite
default though.

[Scheme, as defined by the standard, is case-insensitive, right?
R4RS says it is, dunno what changes in R5RS.]

	* hobbit.scm (*case-sensitive-flag*): New configuration variable.
	(display-var): Use it.
