SWAT renamed, improved descriptions

[Reebs]

You may aswell revert everything the old staff team changed, since you had no input into them either ways and now you're scraping the updates the old staff team thought carefully on.

It would be counter productive to do so. New models were on the way anyway when Mavis got demoted, and that staff team saved everyone time. As far as I'm aware, the old staff parted on mostly friendly terms. The updated weren't scrapped, as the firetruck got updated. They're still coming, just not exactly how the old Staff Team planned it. 

Personally, I think this was a mistake to rename it back to SRU because SWAT is more realistic in my opinion. However, that's nothing that /teamname can't fix. 

As for the descriptions: it should help new players a lot. Good job!
