nGhost Media Center Code

* Lots of stuff was failing to install headers. Fixed, but not sure why
the other syntax did not work (it should have)
* Added "fslistbox" class to the project, as things will not compile
without it. Luckily, enough work has been done that it _does_ compile :/
* Removed yet another reference to 'basedb.hpp', replacing it with
'basedb.h'

added fslistbox files

applied IonIdea-dev's patch for filesystem based listbox

* Forgot to update the install path for a couple of client plugin utilities

* Made an effort to make configuration changes work more smoothly - each section of libnghost now has its own library checks and lookups

removed deprecated desktop stuff

fixed a number of errors and warnings

* Fixed the remainder of the header hell issues by fixing basedb.hpp (basedb.hpp was split into basedb.h and basedb.cpp to keep Qt headers out of nghost headers)

* Removed unnecessary header hell fix in input.h

* Fixed some header hell issues in gui2 library (still needs more work, but it compiles now)
