Project Pampa request: FCurves normalized display

Added two options to a header of FCurve editor:

- Normalize which makes it so every individual
  curve is fit into -1..1 space.

- Auto-normalize, which probably is to be called
  "Lock" which "locks" curve normalization scale.
  This is useful to prevent curves from jumping
  around when tweaking it.

It's debatable whether it need to be a button to
normalize curves n purpose only, and it's fully
depends on animator's workflow.

Here during Project Pampa we've got Francesco
who get used to auto-renormalization and Hjalti
who prefers locked behavior.

Docs are to be ready soon by Francesco.
Thanks Brecht for the review!
