Added ${ORXONOX_LIBRARY_BIN_DIR} which represents the binary directory for the external dlls on windows.
Restructured concepts in bin/ dir:
All files in bin/Release or bin/Debug get configured and copied to the output directory. Configure means setting all the variables marked with @Var@.
MinSizeRel and RelWithDebInfo are considered Release versions.
If there is not specialised file in bin/Debug resp. bin/Release, the file in bin/ is configured and copied.
orxonox.ini gets configured with the available plugins (release and debug), the plugins folder and the media directory.
Also the debug levels have been adjusted for Debug resp. Release versions of orxonox.ini
When not using multi-config (debug, release, etc.) generator (like msvc or xcode), a run script called run (unix) or run.bat (windows) is configured in the root directory.
For tardis, ogre.cfg is copied as well due to a yet unknown bug with fonts for the ogre gui
moved all old style msvc project files to visual_studio folder (that only includes configured output files)
This commit also makes the visual studio files run in all configurations (tested only on my box).
