All basics are implemented. Missing are the right (localized) strings
and the page markup could have a look at by a frontend guy.

- POST /user/repos
- POST /org/:org/repos

Removed trailing whitespaces with

```sh
for file in `grep -r " $" * | cut -d : -f 1 | sort | uniq | grep -v " "`; do sed -i 's/[ \t]*$//' $file; done
```

and some handwork.
