Do not merge.
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
