Make Client and Server Side Formatters Same

Hi.
The formatters available for client side and server side are not same. There are a few formatters that might only make sense on server/client side, but most should be same - both in terms of availability and functionality.

1. Formatters like hasItems, encode, decode etc should be available on both client and server side.
2. Formatters like where, split, join etc should have the same syntax on both client and server side.

The second point would be a breaking change, but a good change to implement. I would not mind refactoring hundreds of lines of codes in various projects, if this is rolled out with prior warning/notification.
