Detect installed mods

[paulhobbel]

Detect the already installed mods and only update the mods whose are outdated.

This does come with some edge cases:

• What to do if a mod is outdated?
• What to do if two mods need the same dependency, but a different version?

There are probably more to be answered

Idea on how it should work:

1. Read enabled mods from ModList.txt
2. Load dependency graph based on those mods
3. Generate dependency graph of mod to be installed
4. Merge dependency graphs together
5. Check which mods are outdated and if there are any conflicts
6. Install missing/outdated mods
