Proposal: Clarify & Expand Delegates and Redefine the General Meeting

The change primarily clarifies the role of the Delegates, and makes it clear that the General Meeting is a meating of the Delegates and the Board, with more clearly defined tasks and prerogatives. The requirements for the Delegate selection are also defined more strictly.

Additionally, this change introduces non-national delegates, to enable the representation of groups and fandoms that are not national. As one of the goals of the Society is to better connect fans across Europe, we should also enable such connected groups to have a say in the Society.
