Converter_ACDC: Add isolation lines
Fixes https://github.com/KiCad/kicad-symbols/issues/429
Please, contribute with ideas for Vigortronix converters: In the datasheet looks like FG is not connected (http://www.vigortronix.com/15WattSMPSPCBModuleAC-DC) but it is included. Can anybody tell me what is this used for? Should I delete that pin? I would avoid moving that pin if possible.
