Music Blocks Release 2.1

This is a maintenance release of Music Blocks. It is prompted primarily by some new translations and a tweak to the synthesizer interface that has a major impact on performance.

Specific changes of notes:

• Update to Aymara by Edgar Quispe
• Revert to initializing synthesizers on demand (improves performance on small devices)
• New examples by Devin Ulibarri: interactive scales, simple crab canon, harmony, fifths and sixths with thirds then circle 4ths
• Other new examples: music tree, fifths and sixths
• Improvements to the scale degree code (#833)
• Fixed problem with nested transposition blocks (#831)
• Fixed problem with flats and sharps when playing backwards (#828)
• Fixed playback problems (#813 #810)
• Fixed some issues with copy/paste (#809)
• Enabled notes to be embedded inside notes (#803)
• Fixed problem with interval blocks
• Fixed table of contents in the Guide (#808)

Tip of the hat to Devin Ulibarri, Edgar Quispe, and Euan Ong for their contributions to this release.
