Update mgerrit activities

Update progaurd to keep classes used by reflection

Patch Set 2: include android-support-v4 library in Android.mk

Patch Set 3: Don't include authority in ROMControl manifest as it
causes INSTALL_FAILED_CONFLICTING_PROVIDER if users installs the
market edition alongside the embedded version (Still works as
as expected because authority is handled directly by mGerrit)
