tex-circuitikz{,-doc}: update to 1.4.6

A nasty bug fix and some hack to avoid that some global Ti*k*Z option
spill into the shapes.

- Fix bug with legacy transmission lines in `overlay`s
- Robustify some shapes: do not let arrows option pass
  to the inner drawing
- Add warning about global draw options in the manual
- Fixes in the documentation: hyperlink the index again,
  cite new recovery point, remove some legacy construct
- Added 1.4.6 rollback point
