(svn r15541) -Revert (r15399): 'v->cargo_type' is also used in other places, which cannot accept CT_INVALID.
-Codechange: Add Engine::GetDefaultCargoType() and Engine::CanCarryCargo() and use them.
-Fix [FS#2617]: When articulated parts have no available default cargo, use the cargo type of the first part for livery selection.
-Change: To decide whether a vehicle is refittable do not test its current capacity for being zero, but always use the 'capacity property'.
Note: The property is used unmodifed without calling CB 15/36. By setting it to a non-zero value and returning zero in the callback vehicles can be refitted to/from zero capacity for e.g. livery effects.
Note: It is intentional that you cannot control refittability by CB 36.

(svn r13225) -Fix (r13041): Missing calls to FindWindowPlacementAndResize() from lots
of windows causing 'two stage' opening effect.

(svn r11374) -Codechange: Give meaning to the magical number that specifies the color of the text in a DrawString call.
Patch heavily based on BiBB's work (FS#1383)

(svn r10258) -Codechange: as we are now using int64 all over the place, it's better to use int64 variables in the string generating too instead of packing them into two int32s.
-Fix: some displays of money were wrong.

(svn r8862) -Cleanup: doxygen changes, again. Mostly @files missing tags and a few comments style.
Some documentation addition, when i can easily supply them

(svn r8455) -Codechange: Give a more meaningful name (railveh_type)to member flags of RailVehInfo, as well as changing the code to reflect the fact that it was not a flag but rather a one value only variable. Doing so, some evaluations have been simplified.
-Codechange: Add and use RAILVEH_SINGLEHEAD when railveh_type is set to 0, which was implicit before.
-Cleanup: Remove some extraneous parenthesis.

(svn r8385) -Fix

-Regression (r8314): I only did half the necessary changes to move railtype from Engine to RailVehicleInfo. Now do the rest.

(svn r8128) -Codechange: Split sprite and palette remap into separate 32 bit values.
This lets us increase the sprite width from 14 to up to 29 bits,
effectively nulling the old sprite limit. Table changes in next commit.
