Frameworks: IME cursor controll be consistent

If user has enabled volume button IME cursor control do not show
navbar IME cursor control. One is enough and can be asumed to be the
default one the user is using. So be consistent and just have one enabled.

Framework: Minor shake to secure fixes

Match insecure lockscreen feel completely:
	Allow camera roll to be viewed while
		shake to secure enabled and
		device is currently insecure
	Launch activities as though insecure
		which makes the process faster
		and uses the correct animation
