Tweak buttons on CC:Tweaked's turtle GUI

[vico93]

Basically, when opening a turtle GUI (image below), two misaligned sort buttons appear, the top right one sort the turtle inventory section (i dont know if this can lead to bugs) while the bottom right (closest to the turtle inventory section, ironically) sort the player inventory.

Obviously the placement of the buttons aren't the ideal (in fact they are widely separated from the inventory they aim to sort), so i'm thinking if would be possible for InvSorter to tweak the placement for that GUI, or if not add that to the blacklist altoghether.

Pinging @SquidDev if @kyrptonaught needs some help with technical details like the GUI id and other stuff.
