Guix,

A quick hack requested by lle-bout: indicate CVE severity with
pretty/scary colours[0].  It's deliberately simple: no scoring, no 
versioning, no importing (guix colors) from (guix cve), ...

Another patch adds order to the rainbow.  Sort CVEs by ID, so 
roughly
chronological.  In combination with the other patch, I prefer this 
to
more complex ordering and/or grouping by severity.

Kind regards,

T G-R
