Merging root folders under new root #112

Related to #111

Adding DCIM/Screenshots as a root before adding DCIM as a root folder is possible even though it's not possible the other way. How do we handle this scenario? Should we automatically add DCIM/Screenshots as a Favorite folder instead, when this happens?

Right now, we don't handle this scenario. What we can do is:

Add the parent as new root.
Convert the child to favorite.
Move tags storage (.ark-tags file) into new root folder.
In case we have several children added as roots already, we need to merge several tags storage into single one.

Good point about content addressing we use for storing tags data is that we don't need to recalculate storage files themselves — only to merge tag entries.

We need to provide a user with these operations:

conversion of root folder into favorite of new root
merging several roots with common parent into favorites of new root These operations should be possible to be invoked manually. If converted root has favorite folders, they must be promoted to favorites of new root.

During attempt of adding new root, we must check if it is parent of any other existing root and call one of these operations automatically (with consent of the user).
