Add QtXml include path for mingw
Fix name of libs for Qt4, MinGW.

Error:
<snip>
c:/mingw-gcc440/bin/../lib/gcc/mingw32/4.4.0/../../../../mingw32/bin/ld.exe: can
not find -lQtCore

The library is named libQtCore4.
Remove prepended unavailable libs, MinGW.
Enable default rtti, it was fno-rtti only on Win32.

The rtti is on by default with g++. It was fno-rtti only for Win32.
However, only qucs/qucs-filter-v2 uses typeid and dynamic_cast.
If needed qucs-filter-v2 need to be hacked to not use typeid and
dynamic_cast, then it is all good for fno-rtti.
Fix progress bar hangs application

The removed piece of MINGW32 ifdef hangs the app.
The progress bar seems fine despite the removed lines.

Running with debug it show the message:

ASSERT: "uint(i) < uint(size())" in file C:/Qt/4.8.5/include/QtCore/../../src/corelib/tools/qstring.h, line 699
Switch back to use strtod on Windows.

The current redefinition of strtod (strtod_faster) is slower.
This redefinition dates back to 2006. It seems that strtod improved
since them.
Loading a 4MB dataset was taking 6s, hanging the application.
With this change it loads in less than 1s.

Removed unused header.
