Add effects list

[AdamRaichu]

This adds effects.txt, which contains a list of the namespaces you can use with iMessage by default. I got these having a friend text me wit each effect, and while I didn't check them all, I checked a couple and confirmed that he received the effect.

I found this list, you have all the bubble effects but is missing a few screen effects

Bubbles:

com.apple.MobileSMS.expressivesend.invisibleink com.apple.MobileSMS.expressivesend.gentle com.apple.MobileSMS.expressivesend.loud com.apple.MobileSMS.expressivesend.impact

Screen

com.apple.messages.effect.CKConfettiEffect com.apple.messages.effect.CKEchoEffect com.apple.messages.effect.CKFireworksEffect com.apple.messages.effect.CKHappyBirthdayEffect com.apple.messages.effect.CKHeartEffect com.apple.messages.effect.CKLasersEffect com.apple.messages.effect.CKShootingStarEffect com.apple.messages.effect.CKSparklesEffect com.apple.messages.effect.CKSpotlightEffect
