VC++ build 220813

[Elstar`]

Tested on Win7 x64.

Differences vs mingw build 220720:

* I wondered, why the installer size was bigger by several megabytes than in mingw builds... Well, there's "Uninstall Avidemux VC++ 64bits.exe" using 19MB, I guess, it is not a simple uninstaller but some autoupdate/uninstall utility for developers (it requires login/password and repository), but why use this in public builds?

* There is no sound on error popups, like "cannot go to previous keyframe". Actually, no sound on any popups.

* There is no "MP4v2" muxer... Well, it was bugged anyways.

Because it uses QtIF (Qt installer framework) which has to include static Qt libraries in order to funciton (it cannot rely on Qt in the right version being already present on the system).

Thank goodness. When Avidemux in the future stops using modal dialogs to communicate errors or warnings to the user and starts using platform-specific notifications, there might be a sound.

Correct, it is obsolete and deprecated and the library it depends upon doesn't build with Microsoft Visual Studio.
