The UI for setting the 'anonymous' option was removed in
f17f5d3f257e2359d4728ce8c296d70dc5e7609f ("PKCE OAuth2 access to cAPI").
Since then there's been no way for a user to set, or unset, this option
(and the associated custom uploaderID). However anyone with the registry keys
still set would have had them take effect.
This commit removes the last bits of code that were making use of it.
Note that the EDDN Relay anonymises all uploaderID values, so no listener
has been seeing the 'raw' values for a long time now.
close#575
I removed most of the overly complex oneliners for equivalent multi-line
constructs. The code behaviour should remain the same.
Otherwise mostly reformatting happened here, spaces after commas, that
sort of thing.
