Version 2.13 calendar parser info, HELP!!!!

[sdetweil]

in 2.13 we are fixing the calendar handling for multiple timezones and non IANA timezone names.
but to do this we are switching the library we use from ical.js to node-ical.

currently in the develop branch the ical.js library is removed…

any non-default calendar modules using the ical library will fail…

are there any? CalendarExt2 uses its own copy of ical.js
MMM-MyCalendar uses vendor/ical (which is broken already in 2.12)

2.13 is coming next week… help
