Multiple Linedef sector tags for each linedef

[Yangguang]

I came across the idea that, it would make things a lot more efficient if each linedef and sector could have a second tag, third tag. At least second tags would be quite preferable. Or else, sometimes you would have to make double, triple amount of dummy sectors just cause it doesnt currently allow more tags. This actually mean that, if sector tag 1 has a 3d floor, and some sector that uses that tag, also wants to use tag 20 which is a transfer light, then its just easy to fill in that. Or else you need to have a tag 1 and some other tag for the same thing except that one of them has that transfer light too.
I hope you do not see this as some requirement from my side, just some suggestion I thought should be doable and make things easier in the future and save rendering speed
