[Reverted] Multiple Routes with 1 Aircraft

[Unknown98]

Alright so we're still having issues with this multi routes thing. (For once even I am also seeing the issues with my own airline, lol)

For now I will have to revert back to the old system while I try to re-write the code to enable muti-route support.

Keep in mind you can still use a form of multi-routes even with the old system, as long as each route starts from a different airport. For example you cannot do:

LAX-HND-LAX
LAX-KIX-LAX

But you CAN do:

HND-LAX-KIX
KIX-LAX-HND

Same routes but in a different order. Get creative with it and you can probably make some things work.
