FC Alliances

[SXTC]

Allow FC's to form an alliance with up to 2 other FC's.

What you may expect:

- Adds the ability to teleport to not only your own FC plot, but also that of allied FC's.
(if no plot is owned, you can manually set an allied plot to be used to teleport to)

- Allies will be able to make use of the NPC's, retainers, stables (but not the gardens or FC vault). If they click on the vault they'll just see their own.
But a shared tab would be added to each FC where they can allow other FC's to see it and take it out or donate (like a secondary tab).

- Allies now have another chat function they can use named "FC Alliance requests" which can be used to request help for a duty without the need for a linkshell.
(This chat option will only be visible while you have an alliance with another FC)

- Link parties for a duty so that if you meet the duty requirements (in terms of jobs required and amount of people) both parties will get priority to end up in the same duty which is useful if you want to do pvp matches.
(now the system only allows 4 in a party to join PVP, but in this situation it would be 4 from each alliance being part of the same group)

The last option is just a bonus though, its the 3 first that matter the most.
