[plt-scheme] Version Check

I'm all for accessing the web on a periodic basis to check for updates
(daily doesn't bother me, but weekly is okay).

The one thing I would like - and it might already do it - is to have an
option that would also check for new pre-release versions.  I tend to have
one of my machines at the latest pre-release.

>     PLT Scheme v317 is now available
>     [Quit & Take Me There]  [[Remind Me Later]]  [Stop Checking]
> The first starts a browser page on download.plt-scheme.org and quits
