Configurable Action Types

• introduce undoType and redoType in config
• if specified, use that as the action type for undo/redo instead of the default action types: @@redux-undo/UNDO and @@redux-undo/REDO

Enhanced Reducers

• redux-undo is an enhanced reducer / higher order reducer (undoable) instead of a store enhancer now
• this makes so many things so much cleaner, have a read of #1 and #2
