Do not merge.

This is a cherry-pick from froyo change I392406824607e2bdae646e3156433d82a9ed6521
Revise NotePad application to use better practices such as
        - inflating menus from XML and supporting API Level 3 without the need
        for version qualifiers on resource directories.
        - to NOT include items in the options menu based on the 'selected' item
        (that's what a context menu is for).
        - include all drawables in the app, instead of using system resources.

        Add features:
        - the ability to edit the note title through the context menu
        - disable menu items in the editor based on menu groups
        - add a "save" button to the editor instead of assuming BACK functionality
        - and show the title of the current note in the activity title.
        - and probably others
