Enable ETWS setting via Setting and MMS apps.
Move general alert settings from developer preference category
to emergency preference category, and enable for ETWS builds and
when developer options is enabled.
CMAS settings are moved to the emergency alert category, and
removed individually for non-CMAS builds. The general alert
settings are removed individually for CMAS builds, unless
developer options are enabled. This satisfies requirements
for ETWS carriers (who do want those options available)
and CMAS carriers (who don't want those options and don't
want a separate preference category for CMAS).
Also disabled ETWS settings in the default config.xml
(used for CMAS). ETWS is enabled in the DoCoMo overlay.
