EO2 Party Bug Fix!

[Whackeddie99]

This fixes a bug which puts you in the party twice if you send a player an invite, he sends you one, they accept your invite and then you accept theirs.

Server side, find Sub HandleAcceptParty and replace it with this:

```
Sub HandleAcceptParty(ByVal index As Long, ByRef Data() As Byte, ByVal StartAddr As Long, ByVal ExtraVar As Long)
    If TempPlayer(index).inParty Then
        PlayerMsg index, "You are already in a party!", BrightRed
        Exit Sub
    End If
    Party_InviteAccept TempPlayer(index).partyInvite, index
End Sub
```
It simply checks if they are in a party first, and if they are it sends them a message saying they're in a party already. (:

nice!!!

I didn't realize this was a problem… that could lead to a MAJOR cheating problem if my Party level system is used without this!

I give this the Party level system stamp of recommendation!

Not for me it wasn't…what are you using??

EDIT: downloaded a fresh EO2 to see and this is what there is:

```
Sub HandleAcceptParty(ByVal index As Long, ByRef Data() As Byte, ByVal StartAddr As Long, ByVal ExtraVar As Long)
    Party_InviteAccept TempPlayer(index).partyInvite, index
End Sub
```
DOUBLE EDIT: I see what you mean, the Party_InviteAccept sub. I know it's their, but it doesn't actually work for some reason. You need this or it will fuck it up. This bug fix works.
