refactor(RD): move success callbacks from ModModel to ResourceModel
While implementing the resource pack downloader in another branch, I noticed that most of the code in the success callback was identical in both cases, safe for a few minute differences in strings. So, this tries to make it easier to share this piece of code. However, it still leaves the possibility of extending the methods in ResourceModel to accomodate for cases where this similarity may not hold. Signed-off-by: flow <flowlnlnln@gmail.com>
