Quote arguments given to Scons

* Just in case filenames might contain spaces.
fix for TypeError: not all arguments converted during string formatting
Debian: Override lintian tag that is not an issue with Nuitka at all.
Fix, was not properly protecting against spaces in paths. Fix for Issue#106.

* The inline copy of Scons was called with wrong path, failing on Windows
  in case there was a space in where Nuitka was installed.

* Compiling programs with spaces in their names cut of those paths and
  failed.

* Added test case for program with space in its name.
New hotfix release.
