Long informative texts causes messagebox to grow outside of screen area

Currently if we launch QMessageBox::aboutQt(), the dialog grows
too large to fit into any kind of device display.

To fix this, we have added a QTextEdit instead of QLabel into
QMessageBox. QTextEdit automatically adds scrollbars to its content,
if the text won't fit into the designated area.

This change causes error QTBUG-6853. This is due to that QTextEdit
does not support activating external links.
