remove "bg data" deprecated check; use net active/conn

some users having issue with background data connectivity
which is now a deprecated concept on android, and a feature
hidden within the data usage settings dialog.

instead we now check if network is active and connected, which
is the recommended approach.
updated strings to reflect "active network" state check
updated manifest for rc3 bugfix
fixed to auto-boot and reconnect code

user reported issue with "sign in" showing up often
aka their accounts were not staying signed in

i tracked it in part to the new code for using networkinfo state
to check if the connection should be made

it was also related to autoboot process killing feature for
the users that really wanted nothing running the background

i believe i have solved both problems
removed evil OTR error dialog; moved back to toast
updated for rc3
