MacGui: Queue Improvements from travistex
- Add view selection widget to choose "encode by encode" or "pass by pass" view
- Add "Show Detail" button to toggle detailed view on/off

- Revamped the progress strings to give you exact progress.
- New terminology (encodes and passes)
- New toolbar in queue window (not complete, icons need work)
- New files, added to project:
