Ignore duplicate types when overriding components

[joachimvh]

As discussed in #105 (reply in thread)

I used the componentResources as an additional parameter since that is what ConfigPreprocessorComponent did, but I'm not actually sure why/if they're needed since all the resources with the same identifier seem to be the same everywhere. Using the type itself instead of componentResources[type.value] seemed to also work.

Also noticed there was a file with URI constants so used that for the override URIs.

Looks perfect! Released as 5.3.1.

If I remember correctly, this had something to do with resources being created by different object loaders, and that possibly causing issues sometimes.
