Revamp Buff slots

Server side we now have 63 total buff slots for clients
They match RoF/RoF2 and are mapped as 42 long, 20 short, 1 disc

The player is limited to what their clients supports, so
Tit players can have 25 buffs and 12 songs, while other can have more

When you log in, we only load up to the max your client supports,
the rest of the buffs are thrown away

Also changed is the default Max Buff slots for NPCs, they now match Tit (60)
If you are thinking about raising that, here are what some other clients support
Tit - SoF 60, SoD - UF 85, RoF - RoF2 97 (although UI only has 85 slots, you can
edit it if you want more)

Also SoD+ the pet limits match the NPC limits.

This will increase memory usage a bit, but I don't see a solution to that
Plus I think most people want this.
