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).
The icons currently only show Xbox 360 controller labeling. The icon set
also includes icons for PlayStation controllers, so we could extend this
in the future.
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OpenClonk era have been replaced by a single notice ranging from the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.
The new type C4TimeMilliseconds behaves for the most part like a uint32_t but is overflow-proof in comparisons.
In some places, a 0-value (or uint_max) of the variable storing the time had the special meaning "not set yet". This has been resolved by having it as a pointer to C4TimeMilliseconds with NULL meaning that it has not been set yet.
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.
Both classes did the same thing at the same time, with the only difference
that C4GUI::Resource was vaguely more associated with GUI stuff. Some
time ago, C4GUI::Resource could be freed during the game, but not anymore.
This saves some lines of code and one redundant class, but shouldn't change
anything besides progress bar being textured a little earlier during
startup.
