[Uml-devel] Some fixes for sequence diagrams - at least partly very important

One more thing,

One of the common paths was this:

#0  UMLWidget::adjustAssocs(int, int) (x=0, y=0)
    at umlwidget.cpp:749
#1  XyzWidget::calculateSize()
#2  UMLWidget::forceUpdateFontMetrics(QPainter*)
    at umlwidget.cpp:1062
#3  UMLWidget::setFont(QFont)
    at umlwidget.cpp:1043
#4  UMLWidget::loadFromXMI(QDomElement&)
    at umlwidget.cpp:1131
#5  XyzWidget::loadFromXMI(QDomElement&)

So I took the setFont call out from this path and moved to
UMLWidget::activate().
Your adjustAssocs() warning no longer happens for me now.
