Change: Include count of stations per cargo type in station cargo filter.

Cargo types with no stations are shaded to make the list clearer.

Change: Replace long list of cargo filter buttons with a multi-select dropdown list.

As before, hold ctrl while clicking on an item to toggle selections.

Codechange: Add method to replace the content of a dropdown menu.

If necessary the dropdown list window will be resized and scrollbar enabled/disabled.

Codechange: Add parameter to persist dropdown menus.

If a dropdown menu is set to persist, it will not close when an item is selected. It will close as normal if the window loses focus.

Closing the list is the responsibility of the caller.

Fix #12012: Crash when opening orders of another company. (#12013)

Orders window changes tooltip depending on vehicle type but did check if widget exists.

Fix 2fd90960: Missing default vehicles and industry acceptance/production. (#12000)

* Fix 2fd90960: Missing default vehicles and industry acceptance/production.

Some default definitions are used across multiple climate types and relied on climate-independent cargo slot even though they specified a climate-dependent cargo type.

Add MixedCargoType that indirectly allows multiple labels to be specified for these.

Change: Decouple and remove landscape-dependent cargo types. (#11719)

Cargo types of default engines, industries and houses are now specified in terms of label.

Fix #11966: Scrollbar may be incorrect on first opening of text file window. (#11981)

The scrollbar is set up before the true monospace is loaded, so reinitialise the window after loading.

Width was based on actual number of data points instead of possible number of data points.

Fix: Second colour vehicle-type default liveries not being updated

Feature: NewGRF properties to set town production effect and multiplier. (#11947)

Town production effect is modelled on town acceptance (growth) effect, and so takes an original cargo slot for behaviour instead of a direct value.

NewGRF feature 0x0B, property 0x1E, takes 1 byte.

Valid values are:
- 0x00 to behave like passengers
- 0x02 to behave like mail
- 0xFF to behave like other cargo (i.e. not produced.)

If not set, town production effect is set based on the cargo label ('PASS' or 'MAIL').

Town production multiplier allows adjusting the amount of cargo produces when Town Production Effect is set, without needing to use callbacks.

NewGRF feature 0x0B (cargo), property 0x1F, accepts a 2 byte (word) value, similar to the cargo capacity multiplier property. The default value is 256 which means 100%, i.e. normal rate.

Fix: don't use non-owning string pointer in StringParameter (#11952)

The string pointer can become invalid before the reference is
dropped, causing out-of-bound access in windows like ErrorWindow,
or News that copy 10 or 20 parameters for their internals.

Change: Towns generate cargo based on town production effect.

This replaces the fixed handling of passengers and mail.

Codechange: Rename TownEffect to TownAcceptanceEffect.

This makes it clearer that TownEffect only affects acceptance behaviour.
