Closes #436 (and #122?): Add options to disable smooth cables and physics (#488)

* allow disabling smooth cables and render them as straight lines instead

* rename 'disable_smooth_cables' to 'straight_cables'

* missed one in renaming

* fix inverted logic

* add GET param and option to DeviceFilterForm

* fix syntax error

* rename var

* add missing query field

* netbox v4 support
