Will no longer be available in later MySQL versions.

Investigate/test the rather bloated InnoDB engine/alternatives, and ensure syncing still works.

NB: Some users (edge case) may have different auto increment lock modes, this will cause problems, as increments may be non-deterministic, causing issues with replication.

NB: InnoDB uses more storage/memory on MySQL, compared to MyISAM.

NB: COUNT() queries will have a performance impact. Affects /bminfo and stats on the WebUI.

NB: Could start using transactions, to solve issues such as #569.
