Added a new component which tracks touch and sensor events and
also events like showing the bouncer tapping a notification and
others. The collection is enabled when the screen is turned on and
is disabled after the phone is unlocked. The data is saved in a
protobuf file in internal storage in a directory called
"good_touches". There is also an option to collect events which
end with the screen turning off. These are saved in the
"bad_touches" file. Everything is hidden behind the
ENABLE_ANALYTICS flag which is set by default to false and can be
turned on only if Build.IS_DEBUGGABLE is true. Also
behind the ENFORCE_BOUNCER flag the class shows the bouncer before
expanding a notification, showing quick settings or launching an
affordance from one of the bottom corners.
