Dear Pre-Release Candidate version(RC-0).

CLR will collect multiplier +1's in range now.
Multiplier +1's caught by player won't disappear now.
Add/Move background transitions.
Add volume control to options. This make the configuration file
not compatible with older versions. Just delete it!
Modify hge's API so that it can handle real volume and pan values.
Volume value varys from 0 to 1, pan value varys from -1 to 1.
