For safety we're only allowing non-empty folders to be deleted. Ideally,
we should have some kind of undo button. Or some kind of history - since
we do have that with git.

We aren't using it, and if we implement a recursive option it should
somehow showcase which folder it is under. Evernote does it in an
interesting way.
Also make sure the _entities and _entityMap are always in sync.
The NotesFolder is complex enough that it could really use some proper
unit testing. Though since it is so tightly coupled to the FileSystem,
it would be quite an elaborate test to write.
Earlier whenever anything changed we would discard all the Notes +
NotesFolders in memory, and reconstruct the hierarchy. This would means
Notes which haven't changed at all, still need to parsed all over again.
Now we only reload what has actually changed.
This should result in a huge performance boost.
We still shouldn't be loading everything on boot, but that's a different
problem.
A NotesFolder doesn't only change when a note/folder is added or
removed. It is also changed when the contents of the Notes/Folders it
contains have changed.
This is a huge change which involves -
* Implementing Folder renames on the FS + Git level
* Implementing the concept of selecting an item in the FoldersListView,
this feature isn't provided by default, and even now I'm not sure if
the semantics which I've implemented are correct. I haven't
implemented multiple folder selection for now.

Also, we're now one step closer to allowing notes to be renamed (#23)
Folders for now can only be created under the root folder. I cannot seem
to figure out how to design a good interface for designing how to choose
the parent folder.
