Update spelling

Updated some spelling and removed some whitespace.

I find it strange that this page is partly in Norwegian when everything else is in English: https://www.webrebels.org/sponsors

Looks like there is suppose to a Twitter widget on this page: https://www.webrebels.org/tickets
Do you want me to fix it? If the Twitter widget is not suppose to be there I suggest we remove "Latest" at the end. Maybe we want the Twitter widget on a different page?
