[REG 4.0.0 -> 4.0.1] Creator autodetects wrong initialization file for MSVC compilers

1. Have MSVC 2010 or 2013 installed.
2. Start Creator without previous settings.
3. Go to "Tools" -> "Options..." -> "Build & Run" -> "Compilers"
4. Select an autodetected compiler and compare the path in "Initialization" to the one used by MSVC command line tool:

   Version	used by MSVC	found by Creator
   2010 32 bit	<installation directory>\VC\vcvarsall.bat	<installation directory>\VC\bin\vcvars32.bat
   2013 32 bit	<installation directory>\VC\vcvarsall.bat	<installation directory>\VC\bin\vcvars32.bat
   2013 64 bit	<installation directory>\VC\vcvarsall.bat	<installation directory>\VC\bin\x86_amd64\vcvarsx86_amd64.bat

While it still seems possible to build with this, Creator should instead use the same initialization files as Microsoft's tools. In Creator 4.0, this worked correctly.
