Created Moritz.Xml and Moritz.VoiceDef projects

Have begun to clean up Moritz' project structure
and dependencies.
Created Moritz.Midi and Moritz.Symbols projects

Moritz compiles. The new projects are not yet used,
but they will eventually replace the code in other,
higher level projects.
Created the Moritz.Performer project

This will replace the Moritz.AssistantPerformer
project.
Created Moritz.Palettes project
Created Moritz.Algorithm project

Renamed Moritz.VoiceDef --> Moritz.Spec.
Moritz.Algorithm and Moritz.Spec use the latest
versions of their files -- using VoiceDef rather
than Voice to specify new scores.
Added score algorithms to Moritz.Algorithm

The latest versions using VoiceDef not Voice.
Created Moritz.Composer project

This will replace Moritz.AssistantComposer
Re-created the Moritz applcation again
