ORBAT - Add role description before player name, accounting for CBA role description.

I find this makes it a lot easier to figure out who has what role, instead of looking at the listed weapons.

I like it. @beaar what do you think?

My last commit will now always prepend a role description, as it's occured to me that not everyone might use the CBA role desciptions.

If no description is present is will use "Leader" for the group leader and "Member" for all other group members.
