Ticket 411 - [RFE] mods optimizer
Description: If there is a series of identical operations on the same attribute it takes
much longer doing each mod seperately, as opposed to combining the values into
one mod operation. Optimizing this can only safely/efficiently be done to sequential
ops of the same attribute and mod type. Once the chain is broken, the optimization
stops for that particular mod, and we start over on the next mod operation.
