Added itemWithLabel:action:

Buttons can be initialised at the same time as they are used.
Updated the README to include shorter form RIButton creation
Merge pull request #20 from p-l/master

Added shortcut to create RIButton with both label and action
Fixed compiler error in itemWithLabel:action:

When newItem below is of type id, then setAction can match a number of selectors. E.g. UIMenuItem action property which takes SEL types. This fix changes newItem to type RIButtonItem so compiler can marshal parameters for method call correctly. See http://www.cocoawithlove.com/2011/06/big-weakness-of-objective-c-weak-typing.html

	id newItem = [self itemWithLabel:inLabel];
  	[newItem setAction:action];

Create button item array on demand, making sure it's non-nil.

When the alert view is created without using the init method in the category the button items array would be nil, causing the actions associated with new RIButtonItems to not fire. Also sets the delegate if needed.
