Added a weight slider to track which defines how much particular track affects in a final reconstruction. This weight is for sure animateable. Currently it affects on BA step only which in most cases will work just fine. The usecase of this slider is to have it set to 1.0 most of the time where the track is good, but blend it's weight down to 0 when tracker looses the track. This will prevent camera from jump. Tutorial is to be done by Sebastian.
