Proposal: Additional condition types for action7/9

[michael blunck]

I´d like to propose to add two new condition types for use with action7/9, namely

0F - Cargo classes defined are not available (variable is ignored)
10 - Cargo classes defined are available (variable is ignored)

Reason for this is that although it´s possible to "switch off" vehicles for which no appropriate freight is available by using condition types 0B/0C, the same is not possible for vehicles whose cargoes are unknown but only their cargo classes being known.

If a vehicle has no available cargo refits at all it's not available anyway, so there is no need to disable it in the newgrf code.

Makes sense. I was under the impression having seen an oil tanker carrying passengers when no oil available in an ECS game, hehe. I´ll take another look, could have been by a different reason.

Note that the rule "if vehicle is not refittable to anything, it is not available" only applies if the default cargo is "first refittable".

Which incidentally is the only sane value when the vehicle is only refittable by cargo class.
