Overhaul Author Profile handling.
This does a few things:
- It reworks author profiles so they are more "independant artist in the internet age"-friendly, by adding
things like multiple possible contacts, home page contact, suggestions for the author role and changing the
full name section to "nick name".
- It removes the automated KUser default author profile to avoid leaking.
- It puts the author info into new resources folder, named "authorinfo". This way, this information does
not get deleted when deleting the kritarc file.
