Galaxy Gio AOSP-GB

Feel free to merge this to your tree, just got one old Galaxy gio to temporarily replace my broken smartphone and tried your AOSP based rom (great work btw)

Changes are minimal, just the fix to show (H) icon instead of (3G) on hspa data connections, noticed you had one overlay (overlay/frameworks/base/core/res/res/values/arrays.xml) wrong, contents of that file are from config.xml, so just merged them to the real config.xml overlay and added screen on after we unplug usb cable.

Patches merge fine, did a local build to confirm they compile, also flashed fine and working on my GIO.
