Fix all initializer list ordering

[crabmusket]

There are a ton of warnings generated by gcc's -Wreorder. The warning's meaning is explained here. Might not be any actual bugs, but it'd be nice to be on the safe side.

I have seen that there are a lot of -Wreorder warnings generated inside /lib/ files.
I think that is not a good idea to modify this files directly, because they will be overwritten if we update these libraries in future.

What do you think?

[dottools]

Yeah, third party libraries shouldn't be modified unless absolutely necessary to integrate with the engine that otherwise wouldn't be useable.

What @dottools said. I've mentioned before the possibility of using git submodules for our lib dependencies, at least those of them for which that's feasible - in that case maybe we could contribute back to those dependencies, maybe fix some warnings, etc. But that might not be a realistic ideal :p.
