Creating chm files for doxygen tests

By means of  `nmake tests TEST_FLAGS="--xhtml --keep --cfg GENERATE_HTMLHELP=YES --cfg HHC_LOCATION=C:/PROGRA~2/HTMLHE~1/hhc.exe  --cfg SEARCHENGINE=NO" it is possible to generate for each doxygen test an index.chm, but there are a number of problems:
- it is only possible to use extension `.html` so this is now automatically done (configimpl.l) otherwise when opening the file an error is displayed.
- it is not [possible to use "empty" hhc / hhk file (i.e. no `<li>` elements), in this case the files are still generated but not used anymore (error like `error: failed to run html help compiler on index.hhp` e.g. for test 1).
- a full qualified / absolute is not allowed for e.g msc images (test 37) the files should anyway be on the "html" directory so just using the filename in the "hhp" file (`     t << QFileInfo(imageFiles.at(i)).fileName().data() << endl;`)
