replicate spell.cgi

[acrollet]

The spell-checking functionality is a hardcoded call to spell.cgi on the local server - js.vi calls spell.cgi with GET arguments like this:

c35=Suite&c36=Boston

The script returns a text/plain document with suggestions in the body like so:

c35=Suite c36= c36=Boston c36=Bostons c36=boson c36=Bolton
