When connecting to the internet for the first time, the proclamations table is empty.
If the user navigates to Settings -> Proclamations, then the sync.SyncProclamations
function is called. After this function returns, the ProclamationOptions screen
queries the database for proclamations which returns an empty list. Even though
the database was updated, the ProclamationOptions screen's instance of the database
connection was returning empty.
Updated Sync functions to perform proper synchronizations instead of pure downloads.
This means that if something is deleted on the server, it will be deleted on the client as well, instead of just left hanging.
The SyncProclamations function was also updated to perform this way, but while retaining the user's saved list.
