[Ansteorra] Official fighter practices

When this came up back in '05, Modius wrote

For a local fighter practice to be "official", the following must be 
present:

1. A Warranted Marshal or their designated deputy (an authorized marshal who 
is an appointed deputy)

AND

2. A local officer or their designated deputy

These can be the same individual as would be the case with a Local Knight 
Marshal or Local Rapier Marshal.

Note:  If you are holding an armored fighter practice, a warranted armored 
combat marshal must be present; if you are holding a rapier practice, a 
warranted rapier marshal must be present; etc.
