alexandr df114f189c Compile under MSVC: this commit caontais all changes to run MSVC build
1) fix some bugs which appear in runtime:  replace QString::tostdstring() to Foo.toUtf8().constData().

2) Enable start center online community. To use it you need download webengine in your QT lib. see instruction https://musescore.org/en/handbook/developers-handbook/compilation/compile-instructions-windows-visual-studio-2017-wip

3) update install steps. Add additional dlls for webEngine. Add copying dlls and musescore.exe to /msvc.install/bin folder. Run project will work with the "$(ProjectDir)\..\..\msvc.install\bin\MuseScore.exe" specified in Debugging field in mscore project

4) Moving AppVeyor from MinGW to MSVC. Exclude ALL MSVC project from INSTALL project. Exclude ALL from PACKAGE. Remove migw-cmake in script build, add .bat instead. Remove xcopy from 7z archive step

5) Fix warning : Warning C4703 potentially uninitialized local pointer variable '' used; Warning C4456 declaration of '' hides previous local declaration; Warning C4458 declaration of '' hides class member

6) Change path to 11 version wix toolset which created .msi installer package
