Subject: [PATCH] [Bleeding] Add support for ThrownExpBottle and Fish to
 launchProjectile(...). Fixes BUKKIT-1536

Previously, trying to launch a ThrownExpBottle or Fish projectile would
result in an IllegalArgumentException. This commit adds support for both
ThrownExpBottle and Fish, which means that all current projectiles are
now properly supported by this method.
