Hide manual lens correction widgets when not needed

- The comboboxes and their respective labels for manually specifying a
  camera and lens are now hidden when not in manual mode to not confuse
  the user.
- All Lens Correction Profile widgets are now aligned.
- Labels changed to not mislead users - the tool lets you select a lens
  profile, but it does not let you manually specify the individual
  correction parameters as previously implied.

Closes #4995, closes #4997
