The previous implementation didn't behave quite like A-* is supposed to.
After trying to figure out what's causing it and giving up,
I've reimplemented it in a straightforward manner.
Now it seems to work a lot better.
Also increases maximum player path length to 100 steps.
We still only store the first 25 steps in the save file for vanilla
compatibility.
1. Moves more assets-related stuff from `init` to `engine/assets`.
2. Removes `SDL_audiolib` dependency from `soundsample.h`.
3. Cleans up some unused/missing includes.
Done with the following script:
```ruby
Dir["Source/**/*.{h,c,cc,cpp,hpp}"].each do |path|
v = File.read(path)
next if !v.include?("uint32_t") || v.include?("cstdint")
lines = v.lines
line_num = if lines[2].start_with?(" *")
lines.index { |l| l.start_with?(" */") } + 3
else
3
end
lines.insert(line_num, "#include <cstdint>\n")
File.write(path, lines.join(""))
end
```
then fixed-up manually
