v2.0.0 beta 8

Last official release for TEENSY LC!!! :(

Unfortunately this is the last release with official support for teensy LC, after struggling a lot with memory limitations i decide to drop support to keep going with the development of new features that can be run on AVR Mega 2560 and any Teensy >= 3.2.

Keep it acid!

CHANGELOG

• fix numbering display on avr
• change non-implemented undo per clear track on generative page
