[pLog-svn] force post names to be unique

[Jon Daley]

 	I have a feature that I don't know if anyone else cares about. 
And I sort of don't want it on the public user settings, since it requires 
additions to the .htaccess, so I would rather people not stumble across 
it, but rather explicitly want it.
 	If you have your custom url for posts set to /{postname} 
(subdomains enabled) you have to enforce that the slugs across all posts 
in a blog are unique.
 	I have a pretty simple patch that adds a number to the end of the 
slug, and increments it until the name is unique.

 	So, the question is - should I add this into the main code with a 
config option that isn't visible on the settings, and you have to just add 
the row to your sql database if you want to turn it on?
