Archive support for mounted content

[Crystalwarrior]

Is your feature request related to a problem? Please describe.
Current content pipeline is an unmanageable, unmaintainable mess. Files get mixed up frequently, any desired deletions are impossible to enforce without insecure bat files and users are not advanced for this kind of technical insanity.

Describe the solution you'd like
First, a folder in ao client that automatically scans for mounted folders and installs them. Second, support for archives. Finally, a Metadata file that contains information such as author, version, description etc.

Describe alternatives you've considered
Bat files are not a solution. Launcher is not equipped to deal with a steam workshop level of complexity. There is no good alternative provided.

Additional context
we've been dealing this for decades maybe it's about time
