Add MinGW-builds gcc 4.8.2 as Tier 2 platform

Since we now ship an installer with it it certainly qualifies
as Tier 2 (if not even Tier 1...)

This change does not apply to Qt 5.

fix PlatformToolSet tag location in vcxproj files

The PlatformToolSet tag belongs into the PropertyGroup with the label
"Configuration". The former location in an anonymous PropertyGroup
tricked Visual Studio into displaying the right PlatformToolSet but
using its default value. If VS 2010 and VS 2012 are freshly installed
on the same machine, the default toolset for VS 2012 is VS 2010.

Webbrowser example: Fix crash due to deprecated code.

The example uses a Qt Designer form with widgets on a QToolBar
imported from Qt 3 which is not supported in Qt 4 and later.

In the code generated by uic, a QLabel is constructed passing
the toolbar as parent and added to the toolbar using
QToolBar::addWidget() which then causes a crash in Qt 4.

Move the widgets from the form into the class to avoid this.
