[0.79] Replaced deprecated Vec3.fakePool.getVecFromPool and AxisAlignedBB.getAABBPool

In 1.7.10 Lex has removed these two functions and replaced them like:
`Vec3.fakePool.getVecFromPool => Vec3.createVectorHelper`
`AxisAlignedBB.getAABBPool.getAABB => AxisAlignedBB.getBoundingBox`
These two new functions are available in 1.7.2, they are just deprecated as of forge#1120.
