Grid2 v2.9.1

Mists of Pandaria Classic

"Add shields to health percent" option disappeared in MoP prepatch.

I'm no coder but with a quick look it seems Grid2 still only enables that function in Cata and WoW90, I think I got it to work by changing:
StatusHealth.lua in \World of Warcraft_classic\Interface\AddOns\Grid2\modules, line 351 to this:

    elseif Grid2.isCata or Grid2.isMoP then

and
StatusHealth.lua in \World of Warcraft_classic\Interface\AddOns\Grid2Options\modules\statuses,  line 152 to this:

    if Grid2.isWoW90 or Grid2.isCata or Grid2.isMoP then

I havent tested any other functionality that might be related to this since I personaly dont use Grid2, but this seems to fix it, and after a limited test with some selfcasts and some quick math atleast the adding absorb values to health percentage bit seems to work.
