2011-03-23AUDIO: Introduce a new MidiDriver_BASE base class.Max Horn
The actual MidiDriver derives from it. MidiDriver_BASE only provides the minimal API necessary for transmitting MIDI data. The idea is that this is all MidiParser needs, thus allowing us to simplify the various MidiPlayer classes in our engines.

2011-03-22AUDIO: Add pure virtual MidiDriver::isOpen() methodMax Horn
This in turn enables modifying MidiDriver_MPU401::close() to allow it to be called on a midi driver that has not yet been opened. The specific issue that triggered me to make these changes was a crash-upon-quit in HUGO, caused by it instantiating a midi driver, then encountering an error (missing hugo.dat) *before* having opened the new midi driver; the general cleanup code then tries to close the (not yet opened) midi driver -> kaboom Also fixed some engines which were leaking MidiDriver instances.
