title: Run monkeyrunner without the phone plugged to the PC
body: <p>i want to run a python stability test-case with monkeyrunner</p>
  
  <p>however i want to run the script without having the mobile plugged to the PC (because what is measuring is battery life)</p>
  
  <p>Normally I use "monkeyrunner mytest.py "</p>
  
  <p>So the idea would be executing the py script with a monkeyrunner inside the phone.Is that possible?</p>
