Preload 3DEN and Zeus item lists

[commy2]

When merged this pull request will:

• Adds cba_ui_fnc_preload3den to generate the item list used as mission attribute in the editor.
• Adds cba_ui_fnc_preloadCurator to generate the complete item list for the RscAttributeInventory display used on weapon crates in Zeus.
• Adds test_preload.sqf"; unit test to check validity of the preloaded item lists (compares them to the lists you get with vanilla or w/e other modset)

Note that the test requires a previewed mission in 3den for the curator part.

The functions to generate these lists are taken from vanilla, but optimized / ace-ified.

why two seperate functions? seems like they are mostly duplicate code?

[commy2]

BI copy pasted one from the other obviously, but the loops around it are different, and they pushBack a different array format / element orders into the respective lists.
I think this is better as two functions.
