Ender Bucket: Fix a bug with still vs. flowing water and lava when picking up.
Ender Bucket: Add dynamic fluid rendering, based on the amount stored.
Ender Pearl: Give it some more speed, and thus, also range :)
Ender Bow: Adjust the orientation when equipped a bit.
Ender Bow: Fix mode toggling on first use, allow use w/ no target if TP self.
Ender Arrows: Fix and adjust the spawn location, increase the speed.

The recent change to the spawn location caused the arrows to also hit
about a block to the right from the center. The arrows now spawn
closer to the line of sight, but further ahead of the player.

Also increased the arrow speed some more, because OP ftw :p
Ender Bow: Remove a bit of unused code. Mode toggle is handled elsewhere.
Ender Lasso: Fix sneak + right clicking not working on inventories.

I had the doesSneakBypassUse() logic reversed, whoops.
Change Ender Lasso texture to purple. Change creative tab icon to pearl.

Plus added a WIP text to the Ender Bag texture.
Also changed the item registration order for "better grouping"
(only takes effect on new worlds?).
Ender Bucket: Same fix as for the lasso: doesSneakBypassUse should be false.
