Fix CSS ordering for config with multiple entry points

[bawjensen]

Hey, this is a rough draft of a fix for #115. The code I wrote is pretty verbose as I didn't want to pull in any dependencies such as lodash or flatten. Let me know what I can do to improve it and get it ready for merging

@bawjensen thanks for solid PR

[alexander-akait]

@bawjensen can you rebase you PR, thanks!

[bawjensen]

whoops, the history might've gotten a little messed up because I did a git push --force. Anyway, it's rebased now and the merge conflict is gone

@evilebottnawi Can this get merged? I could definitely use this fix

[bawjensen]

@evilebottnawi any update? Or any update from @sokra given you've been assigned?

[alexander-akait]

In near future @sokra will answer, sorry for delay

[sokra]

This should probably be fixed in webpack instead. I'll check how to do this.

[bawjensen]

@sokra you mean that the index2 (which I understand comes from webpack) should already be the correct value?

My understanding is that index2 is a value global to the build, but with multiple entry points you'd want the ordering to be localized to the entry point (and each entry point might have a different ordering).

[sokra]

I guess this could be best solved with a (new) per chunk group index in webpack. index and index2 stay. Already working on a PR to add this to the core.

[bawjensen]

Awesome, thanks for working on that! I'm guessing most of this PR will end up being useless? Except perhaps the unit test

[bawjensen]

@sokra once that PR's posted, will it be mentioned here so that we can follow the progress?

[bawjensen]

@sokra any update? I'm curious if I should import my fork into the project, to have an immediate fix, if the proper fix isn't coming quite yet.

[alexander-akait]

@sokra can we merge and release new version?

[bawjensen]

thanks @sokra and @evilebottnawi!
