Finish adding Makefiles for the Notepad tutorial.

Add the missing makefiles for the non-solution versions of the tutorial
code.  Required providing missing imports in Notepadv2.  Also standardized
white spaces using Source > Correct Indentation in Eclipse and a few
manual changes.  This was done to minimize differences such as:

diff -r Notepadv1 Notepadv1Solution
diff -r Notepadv1Solution/src/com/android/demo/notepad1/ Notepadv2/src/com/android/demo/notepad2/
