Implement a quest system and job board

- The job board is loosely based on Exile III's job board; the dialog is converted from the one contained as a relic of E3 in BoE
- Quest system is loosely based on a mix of Exile III jobs and Blades of Avernum quests
- Talking to a monster (even a hostile one) can now trigger an arbitrary special node

Dialog engine:
- LED's now support wrapped labels
