[plt-scheme] scheme/sandbox and gui stuff?

I think that the main bug that you're seeing has been fixed in the last
couple of days. (The `gui-available?' funrction from
`scheme/gui/dynamic', which the sandbox uses, wasn't working right.)

If I run this now, I get a slightly different error:

 ACK! didn't find drscheme's stackframe when filtering
 . file-or-directory-modify-seconds: file access denied
 (/Users/mflatt/Library/Preferences/org.plt-scheme.prefs.ss read)

This error reflects that the sandbox doesn't let Slideshow access the
preferences file. (The "ACK!" prefix looks like a DrScheme problem
taht's still there.)

Running

 #lang scheme/gui
 (require scheme/sandbox)
 (define e 
   (parameterize ([sandbox-security-guard (current-security-guard)])
     (make-evaluator 'slideshow)))

with the latest in SVN works for me.
