a3aa_overrides: configure CNTO static AI skill

[freghar]

Right now, @freghar_a3aa in the CNTO modset doesn't include the ai component at all. I would like to change that for a few reasons:

• There are additional features we might want to enable
  • Preventing AI from dismounting a vehicle with damaged wheels (unless LAMBS overrides that behavior)
  • Boosting game (client) performance by disabling visibility raycasts of remote AI units (that are on HCs)
• The full 0-1 range of AI skill is unlocked thanks to CfgAISkill and skillAI=1 / precisionAI=1
  • This allows selective overrides by a MM, ie. to make ZSU an actual threat, a strategic marksman reasonably accurate, etc.
• We could basically use off-the-shelf arma-additions without any CNTO specific PBO repacking/removal
• We could experiment with dynamic_skill and how different skill values interact with LAMBS on miniops

This pull request adds a configuration for dynamic_skill that mimics the current static skill setting. This means there will be no change in AI behavior compared to how CNTO has it now. The values seem weird, but they are just 0.5 modified by skillAI/precisionAI modified by the vanilla CfgAISkills, whereas (with the ai component of @freghar_a3aa), these abstractions are stripped away, so the actual "final" values are used.

I chose the addon name (a3aa_overrides) generic enough as I think we could use it for #28 and other cases where customization is supported in a3aa. I'd like to avoid having tons of cnto-additions directories.

PS: Do not merge this until the next https://steamcommunity.com/sharedfiles/filedetails/changelog/1470700937 release (in April).

I'm dropping this.

I've since added some features (CfgBrains tweaks) to my arma-additions that could potentially conflict with LAMBS. Also other features (making AI stay in immobile vehicles, speeding up FPS by not simulating AI visibility on every connected PC for every soldier) have a theoretical potential to conflict with LAMBS.

We could remove them individually, but there wouldn't be much left anyway.
