[Rails-devel] Dynamic company order and other fixes

[Erik V. <eri...@xs...>]

I have finally managed to add a missing feature that affects all games
implemented so far (except 1825): the operating company order is now
dynamic. After each company turn the operating order is recalculated. The OR
panel will be recreated if the order has changed.

I am also gradually fixing and implementing a number of outstanding bugs and
minor requests, many of which come from John David Galt's long list.

Done so far:

- If a company has no train, "No train" is reported below the map instead of
"Withhold".
- Show grayed out "Buy Train" button in the train buying step if the company
has no money, or cannot buy a train for any other reason.
- Fix treasury selling tooltip (which said "buy" instead of "sell").

Erik.
