INTEGRATION: CWS presfixes12 (1.6.12); FILE MERGED

2007/01/29 14:01:57 thb 1.6.12.1: Issue number: #i37778#

Larger slideshow refactoring. Wrote design and coding style manifest,
and adapted the code to actually conform to this. In detail:
 - cleaned up ownership/disposable/weak_ptr story. removed hacks and
   explicit Disposable implementations, where workaround were available
 - removed object mutices, where superfluous
 - reworked EventMultiplexer (using templatized listener class now), added
   more events. EventMultiplexer now serves as a true blackboard
 - reworked directory structure: disjunct parts are now physically separated
   into directories, instantiation happens via factories & abstract interfaces
 - added CursorManager, to make setting mouse cursor less hackish
 - reworked DrawShape, to implement SeparateListener pattern
 - reworked IntrinsicAnimationActivity, to avoid cyclic references
 - modified hyperlink & shape cursor handling to communicate via
   EventMultiplexer
 - renamed & cleaned up files (presentation.cxx now named slideshowimpl.cxx,
   etc.)
 - added first version of the z-order fix to layer/layermanager
 - cleaned up include guards and include syntax
