[plt-scheme] cutting and pasting snips

I can give a reason someone might want to to disable the multimedia format.
The last time I checked, mred could not run files that had been created with
drscheme, and had multimedia snips in them.  I.E.  If your program had snips
in it, you then had to ship it to the client with a drscheme window poping
up behind it, and tell them to ignore the window in the background.

I don't know if this has changed (I did just try to check mred in 352 a
muinite ago to see if it now works with multimedia files, and got the error
message:

dynamic-require: name is not provided: snip-class by module:
|,/home/corey/.plt-scheme/352/collects/guibuilder/readable|

, which strangely is the same error message i was getting when running
drscheme in 352.6 and 352.7, but not in drscheme 352).

If it won't run in mred, that seems to me to be a reasonable motive to stay
with text.

P.S.  I'll also toss out the idea of a external tool that converts
multimedia files on stdin to text files on stdout.
