Ability to choose location of NotesUp.db

[devoldski]

Hi there thank you for a brilliant app.

I use it on multiple machines and have a suggestion that I think wil be useful for many users.
It would be really nice to be able to change the location of NotesDB since I sync my filesystem over multiple machines.

Expected Behavior

I suggest to make it possible to select a custom location for database in preferences

Possible Solution

Keep up the good work.
