hi4hi Muffler v2.0

This one was quick ;)
Added ability to read auto-sms sent by other muffler users. These messages are read and converted into notifications which show up exactly when the earlier called user switches OFF the silent mode. Moreover these notification are clickable and on click will dial the earlier called user.

Receiver

1. Launch Muffler. 
2. Choose timeout.
3. Done

If Caller calls Receiver when Receiver is on silent mode, he gets a sms with the time at which Receiver will come out of silent mode.

  

Caller

1. Calls Receiver
2. If Receiver is on silent mode, he gets a text message with time at which Receiver will come out of silent mode.
3. At this point Caller doesn't even need to look at this sms. Muffler will read the message and create a notification which will show up exactly when Receiver comes out of silent mode. 
4. Caller looks at the notification and clicks it to call the Receiver.
5. Done
