Group name is too restricted #208
Description
Currently only word characters, e.g. letters in the alphabet and numbers, and hyphens are allowed in a group's name.
Given that MMS groups are intended to integrate with pre-existing groups defined externally in an enterprise, e.g. LDAP groups, this is overly prescriptive as often one does not have control over the enterprise's naming conventions. A practical example of this is when there are spaces in an existing group name, e.g. Internal Users, which is currently rejected by MMS.
My proposal is to widen the limitation to all printable characters - regex [ -~], i.e. all characters between space and tilde.
