Perl extensions on Win32

Under win32, the default Perl interpreter called should NOT be perl.exe but wperl.exe as the perl.exe executable is buit to open a console to read from STDIN and write to STDOUT/STDERR although wperl.exe is made for getting its input/output from the calling process.

I didn't found a way to specify the Perl interpreter as it is possible under Linux or MacOS as the file "preference.xml" specified in the docs does not exist on Win32 (maybe a doc leak?).

This should allow to run Perl extensions flawlessly on Win32 by just installing either Active Perl or Strawberry Perl without the need of an extra perl.exe wrapper in the Inkscape directory to call the correct interpreter version...

Inkscape version : all

OS version : all Win32
