remove isnull function

change type to boolean

Implementation of multiple where, that has tableField and fild as a array, 'where' contain the fild 'condition' as a condition (ex.: AND, OR)  of where

Now you can join tables with composite foreign/primary keys using RQF. In the
join attribute just use an array of columns that need to be used in the join

reqQueryFields would duplicate inner joins if the same property appeared in
dims and filter.

This adds the option to have values accepted only by one parameter, instead of
globals, like it was then

It uses a object to set the url fields accepted and it's values, parse the
fields and build the query with the values automagically
