	* src/addrduplicates.c

	* src/addressbook.c
	* src/addressbook_foldersel.c
	* src/editgroup.c
		use tree decorations everywhere AB folders are used (AB tree pane,
		    add address to AB, select AB folder, edit group, custom attr, find dup
		    results), in order to match global style
		make double-clicks in AB's tree pane behave like in MW's folder tree pane:
		    double clicking on groups in tree pane does open the group edit dialog
		    double clicking on other items in tree pane does expand/collapse
		fix a missing space in AB's delete-folder dialog
		fix again edit button sensitivity (thanks to iwkse, this reworks cvs79)

	* src/foldersel.c
		make foldersel dialog show dotted lines according to global (hidden) prefs
