Eat My Dust support

[Hipposgrumm]

DB MODEL CHANGES! I don't know how to deal with those.
Support for EMD's MMO rooms and API token.
Groundwork for group/clan system (hence schema changes).
Only functional for EMD right now (if I implemented it correctly).

Hopefully nothing broke and hopefully databases can be migrated just fine (I just don't know how).
I think it's just adding Group and GroupViking tables with their associated links.

this required to create two new tables in database - for sqlite:

CREATE TABLE "GroupViking" (
    "GroupsId" INTEGER NOT NULL,
    "VikingsId" INTEGER NOT NULL,
    CONSTRAINT "PK_GroupViking" PRIMARY KEY ("GroupsId", "VikingsId"),
    CONSTRAINT "FK_GroupViking_Groups_GroupsId" FOREIGN KEY ("GroupsId") REFERENCES "Groups" ("Id") ON DELETE CASCADE,
    CONSTRAINT "FK_GroupViking_Vikings_VikingsId" FOREIGN KEY ("VikingsId") REFERENCES "Vikings" ("Id") ON DELETE CASCADE
);
CREATE TABLE "Groups" (
    "Id" INTEGER NOT NULL CONSTRAINT "PK_Groups" PRIMARY KEY AUTOINCREMENT,
    "GroupID" TEXT NOT NULL,
    "Name" TEXT NOT NULL,
    "Type" INTEGER NOT NULL,
    "Color" TEXT NOT NULL,
    "Logo" TEXT NOT NULL,
    "ApiKey" TEXT NOT NULL
);
