QmlProfiler: next and previous buttons have now consistent behaviour

Browse Source 
Having them behave differently depending on the locked mode was
confusing.  This patch moves that functionality to the event labels,
thus next and prev just select next and previous events in the
timeline, in strict chronological order.
