Reusable action bar component. The action bar pattern is well documented at Android Patterns.
The action bar component is a Library Project. This means that there's no need to copy-paste resources into your own project, simply add the action bar component as a reference to any project.
ActionBar comes with a convenient IntentAction that makes it easy to create action out of Intents.
Since the ActionBar is a Libary Project all resources will be merged to the project that referencing the ActionBar. The values in the main project will always be used before the default values of the ActionBar.
