Destiny Bond not tracked

[quadraticmuffin]

When a Pokemon uses Destiny Bond, the message from showdown looks like the following:

|move|p1a: Qwilfish|Destiny Bond|p1a: Qwilfish
|-singlemove|p1a: Qwilfish|Destiny Bond

But the AbstractBattle class opts to ignore -singlemove messages, so it doesn't track the usage of Destiny Bond until it actually gets triggered and both Pokemon die, at which point it tracks a message like:

|
|t:|1704578006
|move|p2a: Arceus|Earth Power|p1a: Qwilfish
|-supereffective|p1a: Qwilfish
|-damage|p1a: Qwilfish|0 fnt
|faint|p1a: Qwilfish
|-activate|p1a: Qwilfish|move: Destiny Bond
|faint|p2a: Arceus
|
|upkeep

Surely any agent would find it useful to know when a pokemon has activated Destiny Bond, so that it can avoid KOing. Therefore I propose not to ignore -singlemove messages.

The other locations in Pokemon Showdown that use -singlemove are Glaive Rush, Grudge, and Rage.
