#18 Copy data between repositories

[Anton Andreev]

We can add a "Copy Repository" tab. It will have left and right part.
On both sides you will be able to choose between local and remote repositories. Below that it will be the "Copy" or "Transfer" button.

This way people will be able to transfer their data to a new repository and test if it suits them better.
It will also take less time than first doing an export and then performing an import.
