Add Events to Calendar in Panel

[matdave]

I like having the dropdown calendar in the panel, but it seems relatively useless at the moment.

There's not really a need for a constant large button text that takes you to date and time settings. I don't think people are going to adjust those regularly.

It would be really nice to be able to attach this to my google calendar to see events on each day. I find this feature extremely helpful on Gnome.
