Option for changing the placement of the player's name in decorated actions.

[seisatsu]

For the actions associated with the decoration commands, there should be a way to set an action that doesn't necessarily begin with the player's name, using some token to specify where the name should go. When the token isn't present, the action starts with the player's name by default.

e.g.

> decorate exit 1 fell through the floor.
Seisatsu fell through the floor.
> decorate exit 1 The floor fell out under %u.
The floor fell out under Seisatsu.
