Closes #402 and #407 : Right! Finally nailed this fscking issue to the wall (hopefully).
Modified system log to hold extra information about the class being stored, this lets us pull only the required rows from the event log. This drastically simplifies and speeds up the query. Requires: Database upgrade. Outstanding issues: Query is using filesort despite using correct index. Still much faster than the last method! git-svn-id: https://code.elgg.org/elgg/trunk@2194 36083f99-b078-4883-b0ff-0f9b5a30f544
