PatternModelList tries to add button to immutable List

[RalphBln]

In org.coode.patterns.protege.ui.PatternModelList.getListItemButtons, line 284, a button for instantiating a pattern is supposed to be added to the list of buttons in the annotations view. The problem is that this list is now immutable and adding to it does not work anymore.

PatternModelList is a subclass of org.protege.editor.core.ui.list.MList. The button lists are created using Arrays.asList (which returns an immutable List).

The result is a sequence of UnsupportedOperationExceptions and a hanging UI.
