API C Calendar.EventSetTextureID

Needs summary.
 C_Calendar.EventSetTextureID(textureIndex)
==Arguments==
:;textureIndex: - NOT a FileDataID, but an index relating to the returned table of API_C_Calendar.EventGetTextures. You cannot set a custom texture, or even one outside the chosen event type. Therefore, this function currently only has an effect when using the types Raid and Dungeon.
==Patch changes==
