v1.1.9

Improvements

• Basic support for MIDI files: Only one musical instrument (acoustic grand piano) is dynamically loaded and used for all tracks, in a single MIDI channel schema. No percussion sounds on channel 10. This feature must be improved on the future, but currently covers the basic necessities of most musical activities.
• JClic.js is now also available also in Polish, thanks to Waldemar Stoczkowski!
• Build scripts updated to work with Babel 7

Bug fixes

• Allow projects to have multiple custom skins defined in XML files
