Overworking the whole pagination thing a little.

Pagination now calls a getEmpty function that allows to show "Nothing found" errors without having to check for the size of the resultset on the view. Making code there much more readable.
Fixed a small bug in Models that could generate wrong storing of many to many records if both shared the same key.
Improved the way URL generates a query string.

Today I discovered that PHP includes functions for email validation and url validation without need for complicated Regex expressions inside your own code. I'll take all of those!
