Having @grid-columns variable inside grid-framework mixins prevents simultaneous grid systems

12 -span columns is great for nearly all cases - except creating 5 column layouts.

But I can't create a 10 column system without deleting the 12 column one. And the reason is mainly because @grid-column -variable is called inside the https://github.com/twbs/bootstrap/blob/master/less/mixins/grid-framework.less -mixins.

If @grid-column was passed to the mixin as the default value parameter then creating both 12 and 10 (and whatever) column systems would be easy.

Like instead of this:

.calc-grid-column(@index, @class, @type) when (@type = width) and (@index > 0) {
  .col-@{class}-@{index} {
    width: percentage((@index / @grid-columns));
  }
}

It would be:

.calc-grid-column(@index, @class, @type, @grid-column-count: @grid-columns) when (@type = width) and (@index > 0) {
  .col-@{class}-@{index} {
    width: percentage((@index / @grid-column-count));
  }
}

I already got it to work (SASS version) and I think this would be a logical addition.

Semi-duplicate of #11322. But personally I like the idea.

Per #11322, still probably not going to support this. I don't see much of a use case in the ability to create two or more separate grid systems. That said, it's a small enough change that folks could utilize if they were crazy enough to do so, so if someone wants to open a PR, I'll check it out.

Ok! Thanks for the feedback.
