Game update

The improved Suppressed Demand tooltip and info badge.

Changes

- Manufacturers are now much more responsive about opening new production lines when their backlog grows.

- New lines are triggered by how many days of work are queued instead of raw plane count. This should help esp. with slower-to-build planes like the PAX series.

- New lines also go to the model with the longest queue in days of work instead of the most planes.

- Overhauled the Suppressed Demand badge. See the screenshot!

- AI airlines are now much less aggressive about opening new routes if their existing network is struggling.

- AI stops opening new routes while more than 10% of its routes are congested.

- The airport Congestion tooltip now shows whose fault it is. Maybe it's your competitor's preferred queue!

Bugfixes

- Fixed passengers who prefer an airline that doesn't fly their route waiting instead of just boarding a competitor.

- Fixed demand suppression kicking in way too early.

- Fixed passenger groups losing their place in line when only part of the group fit on a plane.

- Fixed partially-boarded passengers sometimes jumping from the open queue into some preferred queue.

- Fixed passengers who were split across two planes losing their demographic and airline preference.

- Fixed AI airlines ordering planes past their own per-model fleet targets.

- Fixed AI airlines attempting to open new routes and construct buildings way too frequently.

- Fixed the Tourist Destination demand boost silently deleting itself after saving and loading.

- Fixed a multiplayer bug.

- Fixed some minor text issues.
