Updated to version 1.1

Hello, number please...

Version 1.1 update. Just a minor update that makes it less buggy and more fun to play:

* Fixed random crash when the timer runs out (this was due to an uninitialised pointer... whoops!)

* Replaced 5 second automatic restart on the end game screen with a replay button

* Fixed bug where calls would still be active from the previous game upon playing again.

Hope you have fun :)
