Update 1.4.8 for MC1.6.4

New mob added: The Jabberwock!
New effect added: Weight, this will pull
you down reducing jumping, increasing falling damage and also pulling
you to the bottom of rivers, lakes or oceans.
Improved the attack
targeting AI with enemy and ally pack functionality. This means that
some mobs will not compare their pack size with their targets pack size
before deciding whether or not it is safe, such as Ventoraptors and
animal herds. This means that your sheep farm in the plains will be safe
if there is a very large herd and no large groups of Ventoraptors
nearby.
Vanilla mob dungeons will now feature spawners for mobs from
this mod. Any mods that use vanilla methods to get random spawners will
also benefit from this. This applies for mobs that spawn as MONSTER or
WATERCREATURE only and uses their spawn rate where a spawn weight of 8 =
a dungeon spawner chance of 200, the same as a Zombie Spawner chance. 4
= 100 the same for Skeletons and Spiders.

Fixed the weird spawning
issues at last! The spawning still isn't entirely perfect but you should
see plenty of Makas now, etc! Turns out it was the Chunk Spawn Limit
oncifg setting, this has now been removed and the vanilla default of 4
will always be used, it isn't exactly a chunk spawn limit, I'm not
certain what exactly it does but it's nothing like how it is named!
The
default spawn rates have been tweaked again, be sure to delete your
config.
New Global Config Setting added: Allow Mob Taming, setting this
to false will prevent players from being able to tame any mob from this
mod. True by default.
New Global Config Setting added: Allow Mob
Mounting, setting this to false will revent players from being able to
mount their tamed mounts. True by default.
New Mob Setting added: Enable
Default Drops: Setting this to false will remove all the default item
drops from the specific mob (can be set per mob). This is useful if you
want full control over what a specific mob drops.
Setting a mobs Spawn
Weight and/or Spawn Group Max to 0 will prevent it from even trying to
spawn at all what so ever, it won't even be added to the biome spawn
lists, this is good if you want to stop a mob from spawning but don't
want it to be completely disabled, you could also set the Biome Types
and/or Dimensions to NONE.

Greatly reduced the Y-Axis clamp on the
Concapede Segments, this should stop them from sinking into the ground
all the time, they may still go through walls now and again, but it
should be rare and not for long.
