Record button should change to pause when user starts recording, and change to 
resume when user press pause.

The button will change back to record after "Stop" button is clicked.

Play back current only available when "right after" recording.

Rec button becomes pause when play back, then switch to resume when the sound 
is paused.

Clicking stop when sound is play back will force the sound to stop, and every 
UI will reset.

When the record is playing back, user can drag the track bar to the position he 
wants and play back from that position.

If the song is currently playing, pause the song until the track bar is 
finalized and play back from that position immediately;
If the song is currently paused, only seek the the finalized play back 
position, and play back when user resume the playing.

Note only final value is interested.

Currently track bar is updated using a separate thread. However the update has 
severe thread conjunction. Now the solution is some random hack: keep interrupt 
the thread until it responses. This must be solved wisely.

Every time after recording the record will be saved to a temp folder under 
working directory, and display on the list view.

The serial number will be 1, 2, 3 ..., name will be "Rec" + serial no., and 
then the length.

Now should handle in 2 cases:

1. Play back current: restart current sound;
2. Play back from file: pause current sound and open the dialog.

Currently play button can be pressed when the sound is recording, which causes 
some unexpected behaviors.

For now, disable the play button when the sound is recording.
