input: added support for multiple keyevents

- Multiple keyevents can now be send from the command line:

    input keyevent <key code number or name> ...

  Sometimes invoking 'input' repeatedly does not send the events fast
  enough, this change solves the problem by allowing multiple key code
  number or names be added to the command line.
