CalendarInviter eviloz

A panel that opens near the blizz calendar event panel that gives you more information about the players. Before forming a raid, you can know: who is online and who is not, who is on an alt, role of each invited player, how many you have for each role for the selected raid size, who is already in your raid, history of signups, who is signed up but has a low rank so doesnt have spot granted, who signed in the last X minutes. Supports both invite-events and guild-wide-events. If you are not the event owner the apply button has no effect but you can still invite ppl.
