Disable -Wregister on gperf output

Browse Source 
Older versions of gperf use the `register` keyword which is deprecated
in C++17, and warnings are treated as errors.

This disables the warning on gperf's output (colour-names.hh). I also
renamed `colour-names.cc` -> `colour-names.hh` because we're including
it as a header, not compiling it separately.

This resolves #1865.
