Seek gets stuck at end

[blakeelias]

When seeking past the end of the last recorded file, playback gets stuck at the end of the last file and all navigation gets disabled.

Suspected problem in MediaPlayerFragment.jump(int)

Have implemented logic in b2c070 to take care of this issue, but program still throws an exception when user tries to fast forward into the future. MediaPlayer can't load the file with the given name, even though the file exists on the file system.

Possible solution: use a FileObserver to detect when tail file is finished being written.
