PHPulse 3.0.1.4 Errors

It was brought to my attention fairly quickly that the sql in the docs directory is flawed. I have fixed that and will load up the fix for that tonight. I also will be fixing AJAX callback functionality; I had removed the functionality into its own method but realized that it then couldn't access the model object anymore (unless I used dependency injection) so I am just putting the code back the way it was for simplicitys sake (and so I'm not constantly passing around the model object like a cheap blowup doll).

I'll also be getting in some changes to the admin functions and maybe even some additional NEWS functionality if I have time later tonight.
