Apply coordinate offset only to VoxelShape

Browse source 
VoxelShape coordiantes generally are an integer + a sum of powers of
two between [-1, -3]. Most offsets are generally an integer. As
a result, applying an offset to the coordinates generally results
in an error of 0. However, coordinate inputs do not follow such
trends. Thus, when applying an offset to the coordinate input,
there may be some floating point error.

By applying the offset to the VoxelShape coordinates, we can
eliminate additional floating point error.

This change also fixes the inconsistency when using
the single AABB, as input coordinates were not offset
when using the single AABB as the single AABB is already
offset.

Fixes https://github.com/Tuinity/Moonrise/issues/81
This specific issue is caused by floating point error resulting
in the falling anvil's y position becoming around -8E-17 when it
should be 0.
While this is still very comfortably in the collision
epsilon (1.0E-7), this results in the falling anvil's y block
position to become -1 (as the block position is simply
the floor of the coordinate).
