Arab meeting house added, uses the same format as the Southeast Asian palace used by Annam.

Mongols now have a palace based on AoE 2 wonder.

- Nobles' Courts: done.
- Mansions: We probably have enough to build them - Byzantine, Chinese, Persian and Indian. Persian may need editing?
- Warrior Hall: Desert Arab, Low Asian, Nomadic?

Buffer BH#s and TGAs for palaces and meeting houses are WIP.

But?
- Indian and Arab meeting houses are not done, unsure if we really want to make them.

More likely to be required than not. However we are also thinking of disbanding the Sasanian meeting house. Could convert it to the Indian one later. Perhaps.

Changed building_graphics entries, forgot about the appearance of the UIs.

Slowly adding new buildings to this mod:
- High Asian, Roman Meeting Houses added.
- Qara Khitai, Bulgars tested and found to be functional.

New Byzantine building set:

- Palace now has a garden.
- Meeting House is complete, but does not have a buffer.

After much consideration, I have decided that ths Meeting House should receive its own BH3 file.

Last palace has been added to this mod.
