Finally 1.0

It’s been a long time since the last update, and the program changed radically. Too much changes to list them exhaustively.

In short:

• Plugin system: the rendering is entierly done by a script (instead of a .json like before)
• Midi inputs
• Better midi backend, sequencer, etc
• New interface
• Can now navigate inside the midi file
• Much more… (I may forget a lot)

That said, while its marked as v1.0, Primidi is still error prone and far from finished, please report any error or suggestion.
