[Radius Markers] Default missing fields on import to their default values on add

[Raitab]

Something of a nit and weird use-case, but functionality I would appreciate.
I was trying to copy some markers I had, but change the npc ids, but because the id was the same as one that already existed, I couldn't. I tried erasing the id and importing it that way, but there wasn't a log to tell me why it failed. Eventually I pulled down the project and saw that markers are invalid if basically any fields are empty. I didn't want to manually grab the current epoch time or set a random integer for the markers, so I decided to create new markers instead.

I think this could be better, and would let people who are savvy share shorter json strings for imports. If you wanted, it could also let you export less data (delete the attributes for things that aren't visible, for example), then default the data on import and hide all defaulted markers.

I have no idea why I did it that way, and I am currently working on a redesign of the plugin that has already removed that restriction.

This idea is actually already part of the planned redesign. I guess a consequence of this will be that markers copied from another person might look different (e.g. different default colours), but shorter export/import json string is favourable.

Manually increasing/decreasing the marker id by a few numbers is perfectly fine.
