* surfacerole: add virtual destructor
all classes that will be derived from should have a virtual destructor
otherwise deleting an instance via pointer to a base class is undefined
behaviour, layershell/xdgshell hits this with std::default_delete in the
new sharedptr implentation.
* includes: fix missing includes
fix missing includes for no precompiled headers builds, and remove a
redefiniton of a macro already defined in macros.hpp
