Sync file list with file actions

Breadcrumb width calculation fix

Whenever file actions are registered later, now the file lists are
automatically notified.

Added FileActions.addUpdateListener() to be able to receive such
notifications.

This removes the need for apps to manually call FileActions.display()
after registering new actions.

This fixes issues with race conditions when file actions are
registered after the file list was already rendered.

Move webdav class to core master

Office mime types update fix

Rewrote the breadcrumb calculation to be more readable.

Breadcrumb now has a setMaxWidth() method to set the maximum allowed
width which is used to fit the breadcrumbs.

The breadcrumb width is now based on the container width, passed through
setMaxWidth() by the FileList class.

Now using fixed widths for the test crumbs to simulate consistent
widths across browsers which rendering engines might usually yield
different results.
