Caller 0.1.3 * Added a Call Block button to powerkey menu, which is an option rejecting call and add that number to the blacklist when phone is ringing ( button is only visible while call is ative ).

Example: someone call you, call number show up and you think it's a spam or telemarketing number, just press the power key button to bring up the menu and choose block button to reject the call and it also add that number to the blacklist for you. I am still taking my time on the ui version. :-)
