[Radiant] [ANN] Validation Extension

[Chris Parrish]

Just got my Validator Extension polished enough to release:  
http://swankinnovations.svnrepository.com/svn/open/radiant/extensions/validator/tags/v0.1.0/

What It Does:
It adds a button to your edit-page pages to allow the user to validate 
their markup via the W3C's (X)HTML Validator.  A report of the results 
is shown in a separate window.  Also, if your db supports transaction 
roll-backs, it'll even validate the current markup in the page (without 
having to save first).  If your db doesn't - I'm pretty sure it'll 
validate something... but I have *no* idea what.

What It Doesn't Do:
It's only HTML for now (though I'll add CSS validation in short order) 
and it isn't smart enough to prevent you from, say, submitting your 
javascript page for HTML validation.

Other Future Plans:
Since I have to render the current page to validate it, I'll probably 
add a page preview button in there too to take over the role of Sean's 
preview extension (if that's cool with you Sean).  I also plan to add 
link checking in a near release.

For more info and plans, see the README file.

This is an early release but functional.  I'd love any feedback 
(especially if it's in denominations of $50 or $100 ;-) ).
