This tries to make our code a bit more compliant with our code formatting
conventions. For future use, this is the command I used:
git ls-files "*.cpp" "*.h" | xargs sed -i -e 's/[ \t]*$//'
I don't really like this, but I can't think of any better way. It
seems that Lua doesn't like decimal comma at all, so we have to
format the volume settings with a decimal point instead. Otherwise,
all I'll ever get is either full volume or no volume, with nothing
in between.
