Logo is from https://www.ubnt.com/marketing/ - no license from what I could see.
poller and discovery files created by me using devices I have access to.
Added basic Ubiquiti support
Updating to include Pro versions
Added check if $os = linux
Added device_bits over graph
Logo licensing would be nice. Leaving this to @paulgear
I don't think we need to worry about licensing on the logo; they provide it on their web site for exactly the sort of thing we are doing with it.
