Fixed the Gallic swordsmen not beeing recruitable after Researching legionairies

Once again made the Gallic Legionaries recruitable

Update:

Added family tree

Made the starting province 75% graeco-roman.
Changed starting temple to auditorium.

Made confederations possible with other western roman sub-factions, If you confederade you'll be renamed: Roman Empire

Also ported over new unit models from Empire divided. for now this bloats the mod file. I'll see what I can do about that.

Fixed the fact that gallic legionaries weren't recruitable.

they are now recruitable from barracks level 1 and the following infantry upgradeable baracks.

Mind you, you will lose the ability to recruit them if you build the cavalry or skirmisher variants of the recruitment field.

Bugfixes such as:

- Gallic pikemen now actually recruitable in campaign

- Gallic swordsmen now are able to upgrade to Gallic legionaries

- Starter army can be upgraded to Gallic units with the right tech.

- Better main menu Map

Added foederati horse archers.

Recruitable from tier two military cavalry building.

Added two general variants to the main campaign.

Added a custom map in the main menu.

Know issues:
- Generals appear to have no porthole/unit card

Fixed the Limitanei statline

- Added the new units to the campaign.
- Fully functioning garrison and research tree.
- Balanced the new units.

Know issues:
- Faction leader model not the same on campaign map
- Starting army hasn't got the new Gallic units.

Working on a fix for these issues.

Please let me know if you encounter anything!

Thanks!
