[Feature Request] Support for trailers and auto records based on connected vehicle

[rougeSE]

First off, so thankful for what you have done. I have been porting over all my records from another system since this is so superior to what I was using before. Kudos!

I have a few trailers and few updates to LubeLogger would be great.

1. Allow for a fuel type of "None" since there is no engine on most trailers.

2. Be able to "link" a trailer to a tow vehicle and use updates from the tow vehicle like Fuel records to drive "odometer" updates to the trailer to help track mileage on the trailer. This would help track wear on tires and bearings and help with service reminders for greasing and such.

I like this a lot! Also, I think an option to remove the requirement for license plate for adding an asset would be really useful as many of my trailers don't have license plates. VINs and serial numbers are much more useful anyway, which is what I've been using instead of license plates so far, but some homemade trailers don't even have VINs and my OCD dislikes filling the field with dummy data.
