Google calendar integration

[randysim]

Would be good if we can keep google calendars. Don't know how many people use it, but it's a nice feature

kind of hard with deno, gonna take a break before tackling this.

the only tricky part is getting the refresh token

doesn't seem to really work well with deno. if this feature is important, we could create an express server just for this api, though as of now, the only solution seems to be to write our own deno library that can interact with the google api (so if its REALLY important we could pull it off but it'll be a crap ton of work).

edit: or wait for google api deno support.
