Background tasks fail to work under wperl (win32)

If you run padre.exe which is actually calls wperl, STDIN/STDOUT descriptors are invalid.

For example the syntax checker does the following:

Error from open(IO::Handle=GLOB(0x7490b74), <&STDIN): Bad file descriptor at C:/strawberry/perl/site/lib/Capture/Tiny.pm line 65 thread 1

Fixed in r8242 and r8246

A side effect is the popping of black command line windows.

The side effect is totally fixed in r8265
