Display scrollbar in helpwindow

For some reason a QTextBrowser formatted with a stylesheet does not
display scrollbars on Maemo 5 with Qt 4.6/Qt 4.7. To work around this
limitation the helpwindow was modified to consist of a QScrollArea
containing a QLabel - this also eliminates the need for stylesheets.
