Getting ready for Android 4.3 release

- Remove AROMA for i9100 & i9300 (It's just useless and bloats the installation)
- Add ALPHA builds to the script
- Remove support completely for Galaxy S Advance (janice)
- Add the New Nexus 7 (flo) to the build sequence
- Re organize the build sequence (Taken from the analytics)
- Clean up the Build script
- Remove useless techniques that were used due to conflicting device features

Build script still needs to be tested on server though
