Changes to select/affect special nodes

- Select PC node can now select a specific monster, rather than a PC; it's renamed to Select Target
- Damage node no longer allows setting pic to 1 to damage active PC in combat
- Damage node now accepts a sound to accompany the damage
- Damage node now works on monsters
- All affect nodes that can work on monsters no longer get the monster to affect from ex2a - instead, they use the currently selected target

The default target selected when a special node chain begins execution has changed.
- When called in certain contexts (kill/see monster, monster special ability), the monster that triggered the node is the default target.
- In the use/target space contexts, if there's a monster on the space, it's selected as the default target.
- If neither of the above hold and the game is in combat mode, the currently active PC is selected
- Otherwise the previous behavour is used - if the party is split, select the sole PC, otherwise select the whole party.
