Updated wiki with all recent enteries. THANKS for all the submissions

We have a few disagreements / inconsistencies -- more enteries will help resolve those.

Remember provide
- RT or OW
- award type saver/standard/upgrade
- cabin
- O/D region (use UA's region titles, eg not asia but northern asia)
- optional add any pertinent extra info such as mileage, stopover, partner, ....

And if you happen to capture the fare rules include them in a CODE section.
