majalan

Copperbox revision 2499.

I've added a port of ZSnd-Basic - now majalan-basic. 

The example works, but the code is currently problematic. One of Majalan-Core's design principles is that instrument numbers should be resolved at "link time". This is to increase the modularity of scores, it should be possible to code an instrument's performance with out hard coding the instrument number. For example I might want to code a drum part without knowing that a snare drum will always be instrument 7 in the orchestra.

In Majalan-Core, I specify instrument numbers only when I link together all the parts of a score. Majalan-Basic roughly supports this but it is mixed up with the Context code and it is messy.
