Grid2StatusAbsorbs

This module restores the removed absorb-below-max-hp, absorb-above-max-hp, and absorb-total statuses to Grid2.

These absorb-related statuses were removed in a Grid2 refactor. Despite the advice in the ticket https://www.wowace.com/projects/grid2/issues/429, I was unable to reproduce the ideal configuration I had, so I delved into the SVN history and found the desired statuses: absorb-above-max-hp, absorb-below-max-hp, and absorb-total inside StatusAbsorbs.lua in revision 744, the revision just before the refactor. These statuses still work beautifully for my Grid2 configuration and this may be helpful for others who also used these statuses.

All credit for the original code goes to the authors of Grid2, especially Gragagrogog who added StatusAbsorbs.lua in Grid2 SVN revision 701.
