Codechange: Using alias and std::array for company expense storage. (#11273)

This simplifies passing yearly expenses to functions and use of std algorithms.

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

Cleanup: Remove obsolete (Make)EnumPropsT. (#10697)

This was used by the command system to help extract p1/p2 parameters, which no longer happens.

Codechange: Revenue is not the same as Income

Income is revenue minus costs. Let's name things correctly (without breaking the script API).

Fix #9440: negative cargo payments not being handled right

Cargo payments were stored as unsigned integer, but cast to int64 during
application of inflation. However, then being multiplied with a uint64
making the result uint64. So in the end the payment that should have been
negative becomes hugely positive.

Fix #8297: Infrastructure counters for road tunnels, bridges, depots … (#8454)

The previous fix 887e9481ff0e70df6bf93ce15a3899a03f124c50 only worked for roads and failed to consider a multiplier used for the infrastructure totals for tunnels/bridges.
Also, depots and bus/truck stops are counted as 2 road pieces on creation but were only counted as 1 road piece on conversion because the function DiagDirToRoadBits() was used, which only ever returns single-piece road segments.

(svn r18283) -Feature: [NewGRF] Add new price bases for removing industries, building/removing unmovables (new objects), building/removing rail-waypoints/buoys, interacting with town-authority, building foundations, funding primary industries (when not prospecting) and towns.
If a GRF does not set price multipliers for these new prices, but for the previously used ones, the old modifiers will be propagated to the new bases.

(svn r17433) -Codechange: Store cumulated inflation in savegame and compute all prices from that instead of storing all prices separately.
Note: Savegame conversion computes the inflation from max loan. Prices from modified savegames will get lost. TTO savegames will also behave slightly different.
-Change: NewGRF price modifiers now take effect everytime when loading NewGRFs instead of once on gamestart.

(svn r16694) -Fix [FS#2995] (rgradual loading, rnewindustries): only pay for whatever has been actually unloaded and perform the payment when unloading has finished. This fixes, amongst others:
* cheating by starting to unload and after getting paid rushing to the depot to get sold (or unloading, loading and getting paid again for the remainder)
* cargo being dropped onto a station at the moment a stockpiling industry doesn't accept it anymore
* industries getting cargo that has not been unloaded yet and subsequently dumping it back on the station in one go
Note: you will now get paid after the unloading has finished, so you'll have to wait a bit longer for 'your' money.

(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
