Citavi Ethnomusicology Citation Style

I have finally started to make a citavi citation style for ethnomusicology based on APA. Currently, it is still faulty and has still many shortcommings, but the next time I improve it should be beta already. At least this is what  I hope. I upload it anyways, so I will be reminded of the current state the next time I work on it.

Model for this style is the bibliography used in the SEM's journal Ethnomusicology.

PS: Capitlization. Last time I looked, it seemed they take titles in mostly capital letters.
