Feature request: don't delete local mod_repo

[Tranberry]

Expected Behavior:

When clicking Get Kenan Modpack, the mods from the Kenan modpack should be added to the /mod_repo/ directory without clearing or removing any other mods that may have been added previously.

Current Behavior:

When clicking Get Kenan Modpack, the /mod_repo/ directory is cleared and only the mods from the Kenan modpack are added.

Proposed Solution:

Instead of clearing the /mod_repo/ directory, the program could check if the directory matches any of the directories in the modpack zip file. If it doesn't match any, it could prompt the user if they want to delete that directory, giving the user a chance to retain their personally added mods. This way, if the modpack gets shuffled, renamed, or replaced, the program can keep up with it without deleting any mods that the user may have added.

I'd also love a more blatant link (about?) to this repo from the launcher itself, I could not find it when I looked.
