This dep was already there but just being used (as we're using serde). Now we can use it at the db layer which makes neighbor struct creation easier
* Cargo locks are being updated to reflect new dependancy changes
These changes actually reduce the dependancy count overall
+ Adding a very simple table to hold all the neighbors that an instance may want to reference
At some point we may want to support vanity join urls and this would be a good place to reference those
There would also need to be a way for admins to add/edit/remove vanity urls but that's for another patch
