Make main window resizable under Unity: Closes bgo#726705

Unity under Trusty 14.04 simply does not allow the application window
to be resized if a GtkHeaderBar is set as its titlebar.  No
combination of related sizing properties for GtkWindow seems to
change this.

So, for Unity, the --enable-unity configure switch must be used.
This means the main window's decorations will remain.

Require double-click to dismiss calendar popup: Closes bgo#726211

Regression introduced when fixing some tear-down issues with popups.
Hide/show calendars: Closes bgo#725780

This introduces the Calendar Manager, which will be expanded later
to allow the user to add, remove, and configure their calendars.
Right now the only active control in it is to set the visibility
of the calendars.  It's also tied to the EDS setting, meaning
changing visibility in another EDS client (i.e. Evolution) will
be reflected in California.

Buttons in Calendar Manager now display color, active so clicking
