Fix for misbehaving family schedule coordinators (e.g. Cozi, FamilyWall)

[stargazindreamr]

My wife and I have been moving into the family schedule organizer space. We decided to try Cozi. It looked good until I connected it to my shared Outlook calander via ICal URL/file. My meetings that originated with the team in India show up at the wrong time (usually an hour off) and might not show up at all.

For example, I have a stand-up at 7am every weekday. In Cozi this showed up at 7am on the day I connected to the Outlook calendar. The next day it showed up at 6am. And the day after it didn't show up at all. The meeting details in Cozi showed it as "every weekday", though Cozi didn't want to show it every day.

FamilyWall managed to show daily meetings every day, but again at the wrong time.

I spent a bit of time modifying this GAS-ICS-Sync script. I added a boolean to the settings section (adjustToCalTz). When true, all event start/end times are modified to be in local time and the event time zone set to the calendarTz.

Cozi now properly shows my work meetings at the correct time and on the correct days.

If anythinks this is worthwhile or would like to see my code, I'll make it available or put in a pull request....
