Version bump to 0.6.1-alpha.
Make sure `breadcrumb_trail()` can return the breadcrumb trail HTML.
Update changelog.
Importing what should be the final set of changes from Hybrid Core.  All further development should happen directly in this plugin.
Better handling of text strings, particularly handling date/time.  This changes several of the labels to simply "%s", which is is a placeholder for the translated date/time.
Bring breadcrumb-trail.pot up to date.
Add Finnish translation files. Props @samikeijonen
