Add actions and handlers for hello world and quit

Create two actions, "hello-world" and "quit", and add them to the
application (which is an implementation of GActionMap). Connect the
"activate" signal of the actions to handlers. Add an accelerator for
each action, so that they can be triggered with a keyboard shortcut.
