Consolidate the include statements scattered across the code in accordance
with the comment in C4Include.h. The advantages are listed in the same
comment.
Furthermore, it follows llvm-include-order which is the logical
extrapolation of the project's style guideline wherever possible
(C4Include.h being the most-frequent exception).
They never worked properly in network mode because all users would see the changes.
EditorProps, EditorActions and shape delegates now provide the functionality to have custom object editing widgets.
This also fixes a bug with the selection callback causing the object list to act up.
The GTK code does not work with the Qt editor. The simpler SDL2 platform
does, so we have little reason to keep the GTK code.
Note that GTK is still a dependency for mape.

It serializes objects using a selective SaveScenarioObjects script callback and then just executes the generated script. This automatically saves important properties, connects switches and doors, etc.
This change also solves the problem that duplicating an elevator plus case would create two elevator cases.
If execution fails (e.g. because of script errors or because a non-saveable object was duplicated), the method falls back to the legacy duplication method of creating objects with the same prototypes at the same position.
Since LTCG is enabled now, we don't have to define every function inside
the headers for ~xXx super speed xXx~, which means we can strip the
headers down to their bare minimum and reduce interdependencies and
therefore recompilation times by a lot.
Reuse the windows code for this. Both versions had three parts: Enabling
the right menu items, adding the selection-specific ones, and showing the
menu. The second part is now common code, with the platform code in a new
function, since it grew big enough to be worth sharing.
The C++ standard library comes with perfectly fine implementations of
these functions, so there's no point in reimplementing them just for the
hell of it.
Add a C4ShaderCall parameter to tho most important drawing functions, and
make C4DrawGL's CreateSpriteShader public with additional parameters to
specify additional defines and shader slices. C4Sky uses this to compile its
own shader with OC_SKY defined.
