Sort files into folders

[itz-Jana]

Hey all,

I went ahead and tried to sort the files into folders to keep the number < 1000 for all to display on Github.
I sorted them so that different color variations and version (fill, solid, light) are in the same folder and kept them separate otherwise.

Things like phone.arrow.down.right and phone.arrow.right are still separate as I feel like that would make the most sense to me, if I searching for something specific.

Here the rule I used for sorting, for reference:

This would fix #1

I was hoping to split things into just the first filenamepart.notthispart.or.this..., rather than have separate folders for filled, open, and similar. But this is a great start!

I understand. I considered that method, but I felt like it would leave some weird edge cases during automated sorting.

For example, if we were to just take everything before the first dot, that would turn arrow.down.left.video into just arrow, which would not describe it well.
And something like fa-angle-double-down would be a separate thing, as we would then maybe just want the fa-angle part.
But typing this I feel like I found a solution to that as well, I'll try something :D
