Release 8

• The description of the pause button now makes it clear that newly started sounds on a paused channel will be immediately paused.
• Adds a message that mentions when new channels survive a restart.
• Properly identifies sound type when stopping a multiplay channel prematurely.
• Adds a warning when issuing a play multi command with duplicate sounds.
• Deduces when a multiplay channel didn't start because there were more than one MOD included.
• The background channel, 2, is now initially set to OGG.
• It is no longer allowed to change the sound type of channels in a play multi command during play. This would confuse the testing environment.
