Title: Support advanced text column filters.

Allows the user to use advanced filtering in the grids. Very useful for filtering down SKUs and probably many other things.

E.g. many times people want to search for say David and not Davidson and a number only at the end of a string and nowhere else.

LIKE Cooper
LIKE %500

And of course geeks can use REGEXP all day long..

REGEXP ^[[:digit:]]{3}-
