Base Line Style update on basis of events

[abhi93]

For the base line of Timeliner I want to add different style till the active item and different style after that.
This would help me to the tasks which are completed and the tasks which are remaining from just color or appearance of color or dotted line in appearance I can classify.

@abhi93, the timeline currently doesn't support such a feature, but I do understand the significant value it could add. I'll include this as one of the stories for the forthcoming release.
