Hide Playerbot accounts from search, character pages and guild rosters

Playerbots are ordinary accounts, not game masters, so hideGameMasters does
not touch them. On a realm running mod-playerbots that means the armory is
almost entirely bots: 1,377 characters listed, of which about 1,350 are bots.

Adds two options, hideBotAccounts (default true) and botAccountPattern
(default "RNDBOT%"), applied the same way the game master filter already
works: left join the accounts we do not want, then require the join to have
missed. A realm without bots matches nothing, so the default is harmless.

Applied in the search listing, guild rosters, and the character lookup, so a
bot's page 404s rather than rendering.

The pattern is spliced into join clauses the query builder emits as raw SQL,
so it cannot be a bound parameter. It comes from the operator's own config
rather than from a request, but Utils.quoteSqlString quotes it so a stray
apostrophe cannot produce a broken query.

Verified against the live realm:

  listed before  1377
  listed after     27
  Spinnaker, Kdog  shown
  Rarzosh (bot)    hidden
