Refactoring

- Makes doxycfg library more self contained
- renames _doxygen library to doxymain
- Modernizes Debug implementation
- Moves Doxygen::runningTime into Debug
- Moves full version string to libversion
- Removed mentioning of file version in messages (when
  FILE_VERSION_FILTER is used)
- Move substitute functions into QCString
