MusicToolv1.2-beta

MusicTool 1.2 is done!
The main new feature is the addition of tone rows/dodecaphonic series as a supported type!
Most operations on tone rows are implemented as well (inverse, prime, retrograde, retrograde inverse and matrix generation).
To learn about how to use them check out the updated documentation and example files.
The parser was also made a bit cleaner using generic functions. The performance is mostly the same but it's now looking a bit better. The environment parsing and syntax checking is still a mess though.
