Uncouple QueryBuilder [V0.2]

[gin0115]

At present almost all functionality is done by the QueryBuilderHandler and WPDBAdapter.

More of the logic behind, where, sort, select should be abstracted into self contained handlers. This would allow for the statement composing to be handled cleaner.

• Create JSON Handler
• Where Condition Handler
• Table Conditon Handler
• Select Conditon Handler
• Join Conditon Handler

Main goal is mostly to have no logic in the builder, just the methods and have additional services and containers/handlers just pass the data over the adaptor.

Currently data is passed as arrays around the builder, these are unpacked and compact'd when passed around.
