Codechange: Store Colours in Colours type. (#11625)

This reduces casts, some magic numbers, and introduces a bit of type-safety.

Codechange: automatic adding of _t to (u)int types, and WChar to char32_t

Change: Reorganise industry accept/produce arrays. (#10853)

Use a array of struct for each cargo instead of an array for each statistic.
This makes iterating for acceptance and production much simpler.
pct_transported is now calculated when needed.

Codechange: Use IsValidCargoID/IsValidCargoType.

IsValidCargoType() is used only for unmapped IDs.

Feature: Industries with neutral stations (e.g. Oil Rig) only supply/accept cargo to/from their neutral station. (#7234)

This change is a controlled by a game setting, located under Environment ->
Industries which allows toggling the behaviour. It defaults to enabled.

"Company stations can serve industries with attached neutral stations"

When enabled, industries with attached neutral station (such as Oil Rigs) may
also be served by company-owned stations built nearby. This is the traditional
behaviour.

When disabled, these industries may only be served by their neutral station.
Any nearby company-owned stations won't be able to serve them, nor will the
neutral station serve anything else other than the industry.

(svn r17113) -Change [FS#265][FS#2094][FS#2589]: apply the subsidy when subsidy's destination is in station's catchment area and cargo packets originate from subsidy's source
-Change [FS#1134]: subsidies aren't bound to stations after awarding anymore, they still apply to town or industry, no matter what station is used for loading and unloading. Awarded subsidies from older savegames are lost
-Change [NoAI]: due to these changes, AISubsidy::GetSource and AISubsidy::GetDestination now return STATION_INVALID for awarded subsidies

(svn r14332) -Fix[FS#1885]: Balance the monthly random industry changes, by introducing a daily random industry change.
This will allow to perform more changes per month on big maps and less on smaller maps, while not overtaxing the IndustryMonthlyLoop process.
Thanks to frosch, for nice code ideas and rewrites

(svn r14105) -Fix: Some typos that are more grammatical errors, as it seems.
Provided by ln
I've added a little fix on currency.cpp too, why not :)

(svn r12041) -Codechange: Add the loader and the property for action 00 industries, prop 24, nearby station name.
No assignation yet, no real work either.

(svn r11534) -Feature(newgrf): Implement property 23h for Industries.
This will add a cost to the removal of an industry using the cheat magic bulldozer.
Note that the removal of regular or newgrf industries without specified removal cost will have no cost applied to.
This is a difference from original spec, where a default base cost is added.

(svn r10980) -Fix [FS#1158] : This will hopefully fix the case of an assert that happens when an industry uses a special gfx index (tile spec 0xFF). This 0xFF is the sentinel of a special check done for oil rigs, where water need to be around, but no tile will be constructed on it.
Problem is that the upper limit of gfx tiles is currently at 175. So, of course the system will assert with 255 ;)

(svn r10972) -Codechange: Implement the counterpart(GetTranslatedIndustryTileID) of getindustileid of TTDPatch. This allows to ensure that the ID of a tile (taken out of the map or not) is still a valid one regarding the possible override it may have been flagged to.
It is not the strict same thing, but is what we need regarding the slightly different approach we took for newindustries.

(svn r10963) -Revert(10700): Although the idea was good, it was more prone of errors than usefull.
So now, it will be better to jump to the overriden tile when it is been marked as an override
