Typedef all globally used export smart pointer types in one file.

Some of them need to be ordered in STL containers, and thus need
a special comparable wrapper for boost::shared_ptr, defined in
comparable_shared_ptr.h. This also alleviates the typedef hell
present earlier in some export classes :)

Making the timespan pointer comparable should fix bug #4093
