Better satisfaction gameplay

• Make sims act satisfacted or discontent with their jobs with moodlets when: 
  - Receiving the "Work starts in 1 hour" alarm
  - Doing daily tasks
  - Doing promotional tasks

• Give sims positive moodlets when completing milestones;

• Make satisfaction/discontentment influence the fun need.

• Add a satisfaction bar: Instead of just gaining satisfaction points we could get back the satisfaction bar that influences the emotional state of the sims.
