Restructured Project Folders, Updated Readme

Also updated .gitignore to ignore obj folder

Now that the RAM full of zeros bug is fixed there is no need for 2
folders.
Some java files have been updated since I use eclipse for Android
development and it was complaining about some parts of the java code. I
will try to fix these as I go along when I have time. Also sorry about
the massive commit.
Allow Stretch Screen to be disabled in GLES2Rice
Fix a possible resource leak in TextureFilters.cpp for the Rice plugin.

Added new hardware profile
After the update to Jelly Bean, the Galaxy Nexus (TI OMAP4460, PowerVR SGX540) required a new set of polygon offset values to fix the flickering shadows bug.  The new values do not match any of the previous profiles, so I added a new profile.  The profiler checks against both the hardware string "tuna" and the Android version to decide which profile to use.
Fix unstreched frame position (gles2rice)

The frame is now correctly positioned at the center of the screen when
using unstreched mode.
