Cvars in The Dark Mod

This should be a list of Cvars that are currently available in the Dark Mod:

Inventory

tdm_inv_grouping Determines whether or not the user-interface uses inventory grouping. It can be changed on the fly without losing the currently selected item.

0 means to use a T1/T2 style interface. Previous item and Next item are used to scroll through the entire inventory. An empty slot exists between the last and first items of the inventory. Previous group and Next group are not functional.
1 means to use inventory groups. Previous item and Next item are used to scroll through the items in the current group. An empty slot exists between the last and first items of a group. Previous group and Next group are used to scroll through the groups of the current inventory in alphabetical order.
2 is default, meaning to use a T1/T2 style interface but sort the inventory by group. Items within a given group retain their position relative to eachother, but all items in the first group exist before all items in the second group, and so on. Previous item and Next item are used to scroll through the entire inventory. An empty slot exists between the last and first items of the inventory. Previous group and Next group are used to scroll through the groups of the current inventory in alphabetical order.

tdm_inv_opacity : Controls the opacity of the inventory GUI. The range is anywhere from 0 to 1, where 0 makes it totally invisible and 1 makes it fully opaque.
