Make icon set for CalDav event presentation, use in iMIP email.

iMIP e-mails were, as a hack, using filetypes icons for caldav
elements (titles, locations).  This commit creates a folder of
caldav element icons. To start, they are used in iMIP emails,
but eventually should be used by any app that wants to have icon
labels for caldav elements.
