VS2003: changes for older compiler

- nullptr not defined, use nil
- remove unused VCXPROJ with wrong name plMoviePlayer
- std::begin, std::end not defined, conditionally include code for plLocalization::GetLanguageCodes()
      on _MSC_VER >= 1800
- add PLASMA_USE_WEBM to appropriate VS projects
- fix library references to opus, vpx and speex
