oh, good, I saw this PR, and was checking the PMS code, the reason i didn't merge it was because it's a situation that i did not think of when making PMS..

the installed addons are saved with their repository locations locally (on the user's side), i think that changing the repository in the addons list like this wouldn't of updated the new location to all the users..

i'm still thinking of the best way i could make this work for future requirements such as this..

thanks for making the PR btw, you got me thinking of a fail point that i did not predict
