Ticket #942: spellchecker.cfm

<!---
This code uses a CF User Defined Function and should work in CF version 5.0
and up without alteration.

Also if you are hosting your site at an ISP, you will have to check with them
to see if the use of <CFEXECUTE> is allowed. In most cases ISP will not allow
the use of that tag for security reasons. Clients would be able to access each
others files in certain cases.
