Add admin roles to membership

As a member of the TYPO3 Association, I like to edit my membership data and add a logo to my company profile.

AC:

Membership can have roles (one or more relations to fe_user - first fe_user gets the role membership_admin)
The role is added manually via backend

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
