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).
I think C4Game::InitKeyboard relies on the callback targets outliving the
keybindings and every other class is prepared to be deleted before
C4KeyboardInput::Clear(), so needs to hold a ref to the keybinding to
delete that in its destructor.
C4KeyBinding is the class that is used for that, and it sets the reference
count to 1 in the constructor, to represent the reference held in the
owning class.
On the other hand, C4CustomKey gets immediately forgotten by C4Game and the
only reference is held in the keymap.
To prevent this from happening again, make the C4CustomKey constructors
protected and C4Game a friend of the class.
Also remove an unused C4CustomKey constructor.
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.
As discussed in http://forum.openclonk.org/topic_show.pl?tid=2917, I
have merged all copyright notices into a single file and referenced that
merged file from each source file.
For the updated source files, the timeline has been split into three
parts:
1. Pre-RWD code (before 2001)
2. RWD code (2001 through 2009)
3. OpenClonk code (2009 and later)
All pre-RWD copyright notices have been left intact, as have RWD-era
copyright notices where the file did not have a RedWolf design copyright
notice but only individual author ones. All copyright notices of the
OpenClonk era have been replaced by a single notice ranging from the
first recorded year to the current year (2013). Mape code did not get a
OpenClonk Team copyright notice because it is somewhat separate from the
main OpenClonk codebase and has only been touched by Armin Burgmeier.
This time with more manual checking and using git blame -M -C, so that
a few cases of copied code get a copyright notice corresponding to
their initial introduction.
