apply andorid's formatter and add two formmater files to /etc.

First of all, I reformat every source files using `etc/android-formatting.xml` as a Eclipse Formatter.

If you use Eclipse 3.5, use `etc/android-formatting-35.xml` as a Eclipse formatter. Otherwise, use `etc/android-formatting.xml` instead.

Open `Preferences > Java > Code Style > Formatter` and import proper one. After import a formatter to your Eclipse, you can reformatting your files.
