Add exp_statistics plugin for player statistics

Player statistics move out of exp_legacy into their own plugin, with the
totals kept on the controller instead of the PlayerData datastore, which
was never synced anywhere.

The lua module tracks the same statistics with the same rules. Gains are
kept per player as unsent in storage and sent over IPC every 5 minutes
for every player with changes, and for one player when they leave. Sent
values move into the totals the controller gave when the player joined,
so get() is the total on every server either way.

Nothing is resent. The instance plugin sends everything left when the
server stops and drops anything unsent when it starts. A leftover can
only come from a save made before it was sent, such as the autosave
loaded after a crash, so dropping it loses a few minutes at worst but
never counts twice.

The controller adds the deltas to a record per player name in
database/exp_statistics/players.json. Instances fetch a player's totals
on join and hand them to lua over rcon. The web UI gets a sortable table
of every player at /exp_statistics, behind exp_statistics.view.
