Add Ottoman Empire & Navajo Nation to list of countries

There are a few movies produced by the Navajo Nation, considered an autonomous country, and several silent movies produced in the Ottoman Empire, yet neither of these countries are listed in the pull-down menu.

Please add them, so the movies can be listed correctly. Navajo films currently have the USA listed as their production country of origin, and Ottoman films are usually listed as Turkey, though no such country existed at the time (the Ottomans were not all Turks). I know of some Ottoman films not listed on IMDb and I don't want to add them with an inaccurate country.
