DB: Abstracted all ORDER BY clauses in the DB abstraction layer
The ORDER BY was previously specified using an 'order' argument, which would then be directly inserted into the query. The new method is the same as what I used for the public API: two 'sort' and 'reverse' arguments. This should be less error-prone and more readable. This changes quite a lot of code, so I hope I haven't forgotten to update something along the way.
