0023821: Improve qmake project files for Qt samples

Project file extension corrected for VS 2010/2012 solutions
Sources and resource files from Common and Interface sub-foldrs added to qmake project files from their original location.
RES_DIR environment variable redirected to the binary directory, all resource files copied there to keep the source tree intact.
RES_DIR environment variable corrected under Linux/MacOS similalry to Windows.
Makefile generation corrected under MacOS:
- filenames used as the output for the extra compilers instead of the absolute paths.
- mkdir and cp command options corrected
