Calendar integration (Google Calendar, etc.)

[FranciscoKnebel]

Hello, I've been trying out the platform recently. Adding this here as I didn't find any discussions about it.
One big feature that other time-trackers have is a 'calendar' view, which we can filter ('current week', 'last week', 'today', 'yesterday').

Instead of just a table with entries, showing views like 'Current Work Week', with all the entries and allowing to move around entries, updating date/time.

Another helpful thing related to this is sync with Google Calendar, allowing for quick adding entries based on saved events from the calendar, showing as suggestions in the 'calendar' view.

Both these things are details we've seen that would be great inclusions to the workflow using the app.

Thank you for the Suggestions. There is a Discussion for Calendar Views here: #267 but there is none for Integrations into Calendar Services yet, so I'll happily convert this into a discussion for Calendar Integrations, as we handle feature requests in discussions (so people can upvote them).
