Fix project selection (regarding #63)

Registering SelectionListener as normal selection listener and not as
PostSelectionListener fixed the issue. Fixed logic bug in selection of
projects. Now selected projects are counted correctly. If mixed element
types of different projects are selected it counts as none selected.

Add expert view toggle (issue #50)

Expert view can be toggled in the context menu and the setting is
persisted on a per project basis. Open editors/views that are related
with expert view are currently still left untouched when the expert mode
is deactivated. The new feature only affects the display of the
Hierarchy node currently.
