insert campaign and user-templates

[y0014984]

independantly there are campaigns (id, name). They are referenced in missions. If admin creates a template/role, it has to be associated to a campaign. if admin assigns template/role to a user, a user- template is generated. The now can customize and save this template. If a mission starts, ppl checks which campaign is used (how to setup that? With module?) then checks which template is assigned to the unit (module again?), the player has chossen, then it checks if there is a user-template associated with it, then it checks if there is a loadout that is based on the user-template. Then this loadout is loaded.
