Replace "General Settings" with "unprotected Settings" or just "Settings"

[grzesiek2010]

Closes #4892

What has been done to verify that this works as intended?

I reviewed implemented changes and ran automated tests.

Why is this the best possible solution? Were any other approaches considered?

I fixed the strings that contained General settings as described in the issue. Additional I went the extra mile and renamed our methods and comments where instead unprotected.protected settings we still had general/admin settings. I could have done even more an rename local variables but I think it would bow the pr too much so I decided to back off.
