Fixed leak while merging facets.
The ThemeList that is used by OutputHelper to sort the
Facets for an Output now uses a list to store the ManagedFacets.
The correct order is made up by sorting the List using
Collections.sort() function of the Java JDK. Therfore, the
ManagedFacet class implements the Comparable interface. The
return value of its compareTo(other) method depends on the
value of the 'position' field.
