Camera tracking: interface cleanup and small buttons renaming

- Move tracking-related constraints to own section in list
  Currently there are only two constraints, so can look a bit odd,
  but it'll be other constraints like "Object Solver" and so.
- Move motion-tracking parameters from 3D viewport Display panel
  to it's own panel.
- Get rid of "Bundle" in 3d viewport. It's quite obvious that it's
  a 3D representation of tracks is used in 3D viewport and it shouldn't
  be so confusing for artists now.
- Also get rid of "Bundle" in Follow Track constraint.
  Old files can change a bit because of changes in DNA.
- Also get rid of "Bundles" in operator which creates vertices cloud
  from 3D position of tracks.
- Rename "Principal Point" to "Optical Center" in the interface.
