When pushing a local database to the remote server, the new commit id is returned. Grab that id and insert it into the database of local checkouts. If there already is an entry for the given file, update that record. When doing an initial push of a database, also copy the source database file to our checkout directory to avoid redownloading the file upon first use. This should eliminate all unnecessary database downloads, both after doing the initial push and after committing a modified database.
