Consistency fixes & fixed broken CoA for all after e_seljuk_turks

k_seljuk_turks was supposed to be e_seljuk_turks.  k_seljuk_turks had no flag, causing all of the titles defined after it to have incorrect flags.  This included most of the religious head titles but also affected plenty of tribes and titular titles and such.  I don't know whether it was a 2.2 change, but e_seljuk_turks is what has a flag in vanilla (and is in vanilla)-- not k_seljuk_turks, which was there beforehand.

PB also had the same issue, so it was probably a 2.2 change.

I also fixed several consistency errors in title naming in comments while I was at it.
