Make # of Poles & # of Throws editable on Relay(s) -and- add "contactor" as lookup term

[JP-Higgs]

I commonly use multi-pole and multiple throws on my relays and see no built-in straight-forward way to do this as is. If the option to edit the number of each, this would avoid having numerous items added yet cover a large amount of options. Additionally, adding the term "contactor" to the searchable list for relays will make finding those components easier for our friends overseas (and a few in the states as well).

Agreed. I used dual-pole dual-throw relays in my course labs. It would be helpful to have.
