Made the showing and hiding of the search table view behave according to the native equivalent. Eg. hide every time when there is no search text.
Brought back the creation of the address book into init and added it to the initWithCoder:
Added an assert in case those two inits don't cover all cases.
Merge branch 'searchTableHide' into develop
Added a notification when the visible size of the controller changes, so that an embedding view controller can expand/contract the container of the picker.
Split into separate files and other things.
Fixed the token and text frame layout to better accommodate the hint label.
Not animating the search table.
Moved to iOS 6.
Initialising the address book in view did load.
Asking for access to the address book right at the beginning.
Fixed the textField not resizing correctly on the iPad.
Accessibility labels on the tokens.
Supporting iOS 5 again.
