- create plugin.lib that contains all

- distribute plugin.h, api.h and plugin.lib
- remove inc_c stuff because we don't really want to install win32 header files as something that can be used on linux (this should be revisited later)
- fix up MakeFileList for newer versions of SCons (should be removed in the future)
