cleanup string stuff

some strings mess up the scheme -> emacs communication. quickly
patched it, but there's a problem with eval/not eval at some
points. i.e. in scratch buffer :

	(snot-eval '(list->bytes '( 0 0 0 ))) =>
	(string 0 0 0)

and not the string itself.

it's importantto be able to transfer binary data.

problem: snot-eval-reply should process the expression
