Stands and mounts for Biltema Tiny Whoop gates

[Biltema sells quite good gates](http://www.biltema.fi/fi/Vapaa-aika/Urheilu/Kuntoilu/Kahdeksankulmaiset-renkaat-12-kpl-2000041073/) for Tiny Whoop fpv racing.
But native clips are quite shit, so here is the better ones. You can attach 4 or 3 gates together.

There is two version of the stands to rise gates from the floor. Straight up and 40degree angled.
Use two angled stand to hold one gate for more stable standing.

*2019-01-13* Added dress-on foot for an angled stand.
