Allow custom images for data sources and resources that are not natively supported

[Shocktrooper]

I understand that new providers are being supported all the time but even with that there would be a problem with other providers or custom providers that don't have icons. An end user should be able to provide a custom image library for providers so that they show up in the visual how the end user wants it to look.

Hi @Shocktrooper this is a good idea, I agree that this will be necessary, especially for custom providers!

Due to some other, more pressing things we've got to work on (#44 , #52 for example) we have to push this one out a bit, but I labeled it as a feature request and we'll get around to it as soon as we can!
