Large projects were returning an HTTP 500 on the project dashboard, because PHP was running out of memory trying to return every entry for stats to be calculated client-side. This changes the stats to be calculated server-side instead. We get rid of the "number of entries with audio" stat because it's not possible to calculate in a simple Mongo query and would require serializing the entire entry database server-side, causing the very memory error we're trying to get rid of.

Now the lex_stats call opens a single MongoDB connection and reuses it for all three queries. The efficiency boost might be minor, but it's also a slight code simplification so it's just as well to do it now.
