[FEATURE] Mod Management

[Foxlider]

THE feature that FASTER had

KAST need to be able to manage mods as well and probably in a better way
The most difficult thing in FASTER was the updater

Needs :

• Download a mod from Steam (from URL or ID)
• Notify if a mod needs an update
• Update mods
• Fix broken mods
• Efficient storage (don't have dozens of duplicates)
• Local Mods management
• Import from Steam ?
• Import from Arma Preset ?

So far FASTER went through SteamAPI + SteamCMD (yikes) and BytexDigital's Steam Wrapper that works but is still kind of a mess to update

The idea is to make one or multiple Services in the Core to manage Steam integration with SteamKit directly.
