#4 Spell check a remote website by referrer

[DotMG]

Add an option to spell-check an XHTML website that links to the spell checker. The idea is that if the url is /spell/check/referrer , the spellchecker should load the referrer site (if available), strip XHTML tags and spell check it. Then, any malagasy website will be able to link to /spell/check/referrer and any user will only have to follow this link to spell check the site.
