Slice and Dice at last, upgraded weapons and endless fights

Seventh batch of the night: rogues finally cast Slice and Dice, characters with badly outdated weapons buy better ones, fights that never wear down the target are abandoned and a warlock leaves its summoning loop.

Fixes

Rogues: Slice and Dice had never been cast; the spell targeted the rogue itself and the server refused it (329 refusals in six hours for a showcase member). It now targets the monster holding the combo points: 40% more attack speed.
Weapons: a character whose weapon is eight or more levels behind immediately buys the best one it can afford, instead of saving for an unaffordable one.
Endless fights: a fight where the target's health does not drop in three minutes is abandoned; a monster type abandoned three times in thirty minutes is avoided. A death knight kept chaining monsters it never wore down.
Pets: three out-of-combat summons in two and a half minutes and the character leaves the spot; if it happens again, it heads back to its inn.
Loot quests: every quest monster killed counts as progress; a quest with a rare drop is no longer abandoned.
Dungeons: a follower stopped within range and in sight of its tank settles there instead of reporting itself stuck.

Verification

Two paired validations (16 and 20 clones): experience, quests and deaths stable, no crash, no new error; the drop in gold matches the weapon purchases.
