Merge branch 'hotfix/0.4.7.1'
Don't make HTML versions of the manpages anymore, not very useful.

* It's not portable to Windows as well which brought up the issue
  of why.

* The User Manual should now be used instead.
Debian: Added missing dependency for processing PNG images in rst2pdf.
Fix, standalone mode should make sure to include "hex" encoding. Issue#116.

* While doing it, also include UTF-8, which will often be used even when
  it is not the encoding of the system.
Added test case for Issue#116
New hotfix release.
Merge branch 'hotfix/0.4.7.2' into develop
Have "nuitka-run" for immediate execution and compile executable by default.

* Beginners don't get that it takes an option for Nuitka to do the
  correct thing.

* This is an incompatible change warranting version change.
Improved compiler detection

* For amd64, one also needs to have env["CC"], so set it as well from the
  list of candidates.

* Make sure env["CXX"] is None is the compiler does not exist, the scons
  versions seem to make differences here.

* The compiler found error check may have been wrong.
New pre-release.
