Bug 1177545 - Cleanup automation.py.in; r=egao

Remove unused code from automation.py.in, move some android-specific code from
automation.py.in to remoteautomation.py, and eliminate some other easily-replaced
code. In the long term we want to eliminate automation.py.in completely; I may
attempt that once these changes have landed.
