Added scrollbar to phrase bubble in training screen for long phrases.
Review Request #114627 - Created Dec. 22, 2013 and submitted
Added functionality for user to scroll down long phrases in training-screen phrase-text bubble. Used PlasmaComponents.ScrollBar for this purpose.
Good start, but some minor changes are needed: * the margins do not match to the overall design (the scrollbar should have a distance to the right border for example) * is it possible to add a fade out effect at the bottom/top of the text if not everything is shown? * I would prefer to keep bubbles with round corners as it is typical for comics
