I had some spare time at work today so I put together this patch.  It'll
give the more adventurous of you something to play with. :)  I assume
it will also be in v1.0i if there ever is such a beast.

This patch adds two Tcl commands, 'encrypt' and 'decrypt'.  They are of
the form:

encrypt <key> <string>
  returns: encrypted string (in base64 plain text)

decrypt <key> <string>
  returns: original string

Example:

> .tcl set x [encrypt "password" "Blowfish did this."]
Tcl: FT1i4.DMHrz1kNmy1.xGKyt.D3Mon/sj47y.
> .tcl set y [decrypt "password" $x]
Tcl: Blowfish did this.

You could use this to send encrypted communications across the botnet,
or to write your own note system that uses encryption (if you're paranoid)
or whatever.  It's just something extra to play with.
