SpawnMenu Nested Categories!

[Update! Categories are now alphabetized]
This addon will override some sandbox scripts to allow spawnmenu categories to be nested. There are a few built-in methods for categorising a few common entities and addons. Also two bonus postprocess effects! (Check texturize)

If you're an add-on developer, and you want to make use of nested categories all you do is:

In ENT, SWEP, or vehicle list entries, where "Category" is used, just create extra entries that are numbered in the nesting you want.

SWEP.Category1 = "FirstCat" --First Category
SWEP.Category2 = "SecondCat"
SWEP.Category3 = "ThirdCat"
SWEP.Category4... blah blah blah
SWEP.Category5... and so on
it keeps nesting until there isn't another category

the menu falls back onto default category behavior if Category1 is missing.
You can assign the icon on each category using list.Set like so:

list.Set("EntityTreeIcons", "FirstCat.SecondCat.ThirdCat", "icon16/cup.png")

Subcategories will appear among the items in the selected category. You can specify what image to show for the icon for this:
list.Set("EntityTreeThumbnails", "FirstCat.SecondCat.ThirdCat", "entities/baloney.png")

For other types, the format is the same:
-VehicleTreeIcons
-WeaponTreeIcons
-EntityTreeIcons
-GlobalTreeIcons (Will apply to all matching categories)

You can also specify single categories and it will apply to ones that match at the bottom level:

list.Set("GlobalTreeIcons", "Half-Life 2", "games/16/hl2.png")
(gives all instances of "Half-Life 2" the HL2 logo.)

Please let me know if you have any requests for this addon or suggestions!

-TDMCars (Vehicles are categorized by brand)
-Food and Household Items (Food items are divided into subcategories, based on the "kind" of food they are.)
