Overwrite when path or name matches proper or Repack

[lozbrown]

This is actually a duplicate of #84 as i'm not sure why that was closed becuase it's still a very useful request that is not yet possible.

Essentially an additional config item, something like "overwrite_destination_on_repack_proper" which when true would perform a case insensitive pattern match on the full path for Proper or Repack and force overwriting for these files.

thinking about this it might be better to have some sort of pattern list where overide is forced

"force_overwrite_patterns": [{"match": "REPACK ", "is_regex": false}]

Yeh that seems like a good approach, and shouldn't be to hard to implement once the renaming logic is tidied up in the v4.0
