Airline Club

Hi all! I haven been working to improve the passenger simulation with some adjustments and bug fixes and here is the summary of changes:

- Easier to attract business and first class passengers as their quality expectation is lowered
- Passengers are slightly less willing to downgrade (for example from business to economy class)
- Passengers are less willing to switch airlines for transits
- High flight frequency (> 14 per week) will be more attractive to passenger with preference "Swift"
- Business and First class passengers are less sensitive to price changes
- Code optimization to avoid some redundant calculations
- Business and First class passenger favors direct flights more

Running some tests locally before releasing it probably tomorrow (Aug 5) 

I have reverted that change as it removes more transit pax than expected

3 stars quality expectation for business and 3 and a half for first is too low now. Please revert this change too
It kinda makes SQ over 65 worthless.

o the expectation is just what the pax will consider sufficient, if u go beyond the expectation u can charge more without losing pax, and pax will pick ur airline over others that merely deem "sufficient"

This change just make business/first class pax more likely to "accept" a route if there are no alternatives. If there are alternative the same quality comparison logic still applies
