Limit scrubbing to scrub bar in Timeline, Graph and Dope sheet so selection can work the same in all editors.

Hi, Maybe this is just me, but in all the animation editors (Timeline, Graph and Dope sheet) If you click drag anywhere in the editor it scrubs through the animation instead of doing a selection like it does everywhere else in Blender. Right now, when editing animation, I keep accidentally scrubbing instead of selecting because I expect selection to work the same everywhere.

However, there's a nice thick juicy scrub bar on top of the all the animation editor windows that should already serve the purpose of scrubbing through your animation so this seems unnecessary.

What would be nice is to be able to be able to do multi selections on keys the same way you can do multi selections everywhere else without having to use a hotkey.

TLDR

ps: Thanks for the formatting help. It turns out my previous attempts were unsuccessful due to the Imgur links not pointing directly to the images.
