(Feature request) Import/Merge Another Trilium Database Into Current database

[0xbismarck]

Describe feature

I would like to see a new import feature where you can Import an existing database into the current open database of Trilium.

General use case: Working on multiple devices that I would prefer not to export and reimport the html database. I'd prefer to just take the Trilium db from Machine B and import it into Machine A.
