halfway through implementing timestamps:

* still need to use the start position value stored in the PlayVideoActivity's Intent bundle, to set the VideoView using seekTo()
* need to test timestamp extraction regex, and possibly move it somewhere else
*need to find a better way to get the startPosition value to ActionBarHandler, which I thought used VideoInfo objects, but apparently doesn't
    * currently there is a small setStartPosition() method
