Title: NF: check that team names are sane.

Only allow for names that:
1) are pure ASCII
2) are at least 1 char long
3) are at most 25 char long
4) only contain spaces or alphanumeric chars
5) do not consist of spaces only

Support for Unicode can be added when we migrate to Python3.
Right now TK breaks if you have unicode chars that it does not
know how to display. The ascii viewer can not show Unicode properly.
