Stop it being a singleton. This means it needs to be passed around a
lot. This sucks, but it's how it should be. I shouldn't be using a
global variable to get around this.
This is needed as Settings will soon become repo specific when we
support multiple repos.
This breaks saving the settings in a file, that feature was toggled off
anyway. It needs to be thought over again.
This is quick and dirty way of fixing the problem. It doesn't migrate
the notes from the previous repo and just discards them, so you cannot
move your notes from one repo to another using GitJournal (for now), but
at least its better than having to re-install the app.

This contains the default editor / view / sortingMode / etc. For now the
folder settings are shared among all Folders. But the idea is that we
should be able to set different settings per folder (real or virtual)
It doesn't make any difference as -
1. The sort order shown our SortedNotesFolder is different
2. Rebuilds of the tree affect everything. Even the elements which
should be in the correct place.
This is just for optimizing the loading of the Notes in the correct
order. I want to avoid the notes appearing and disappearing in a strange
order when loading. It gives a bad first impression.
This cache isn't integrated, it's only half done.
