Merge branch 'hotfix/0.4.4.2' into develop
Fix, classes need to have full module path as "__module__" attribute.

Corrects Issue#101, the commit tages as well Issue#101 actually is
for Issue#100.
Windows: Restore XML manifest, found a case, where it is needed.
Cleanup vertical whitespace of blocks with temporary variables with multiple statement lines.
Developer Manual: Minor corrections
Cleanups only

* Comments to fit 80 columns.
Portable: Cleanup importing mechanism

* Do not use "PyImport_ExtendInittab" at all anymore. It's not needed,
  and now it stood in the way of extending the description structure.

* Declare our own structure that allows to specify flags. One flag
  might be, that something is a DLL instead of a compiled module.

* Moved unfreezing stuff to its own header file, so declarations can
  be used in both the implementation, and the usage.

* This should not actually change anything yet.
Added test case with relative import from main program inside a package.
Restore ability to run portable setup with Python2.6
Cleanup, move variable trace classes to dedicated module.
Windows: Transport the path of the running Python through to Scons.

* This means installation of Python to C:\PythonXY is not requirement
  anymore if you are using Python2.

* For Python3, the Python2 used to run Scons will still be found only
  if installed to C:Python26 and CPython27.
Added a warning for "--recurse-to" arguments that are not included in the final result.
Added errors for "--recurse-(not-)-to" that appear to be relative or absolute paths over module paths

* This should make it clearer to users that it won't work.
Minor cleanups
Cleanup scons file
Windows: Use registry to locate Python2 for running Scons.
