Author now has Name() over Namer

Prior to this commit, interface Author embedded interface Namer. This
doesn't work, as it is discouraged to keep a working state inside the
implementation of Author, but Namer's embedded Iconer requires a state.

The commit changed Author to use a Name method instead, which is only a
getter. It will no longer satisfy interface Name.
