Bug 502663

SUMMARY
Two automations in kdenlive is interfering with my workflow, and while some people might like it, I would like to be able to turn these off.

**First automation:**
In some cases, when adding an effect to a clip and the playhead is not at the start of the clip, changing the values in the effect adds a keyframe at the playhead position. When you want to adjust the strength of the effect for the whole clip, this is unwanted, and I have to do extra work to remove the added keyframe. 

As a compromise, holding down some modifier key chould add in a keyframe on the effect if values are modified on a position in the clip that does not have a keyframe. 



**Second automation:**
Dragging a clip into a folder in the project bin causes the folder to be expanded. 

In my workflows I separate the clips I have used in the project from the unused ones by putting them in a sub-folder in the project bin. This is to effectively hide them, so I really don't want the folder that I am dropping them into to be expanded. 

Every time I get move clips into the sub-folder I have to then collapse the folder again. This interrupts my "flow" because no other file manager works like that, which is a bit jarring.  

It would be more efficient to just leave the folder in the state that it is in when something is dropped on it. If the user then clicks on the folder it should be expanded, and the clip(s) that were dropped there highlighted. If the user does not click on the folder, the selection should be dropped once the user clicks on something else.
