string-util: accept ":" when stripping ANSI color sequences

Browse Source 
Since 6eabe9f2ff we generate sequences
with ":", hence we better also know how to strip them.

(Without this patch we'd strip simple ANSI colors, but not RGB ones that
use ":" syntax).

(While we are at it, also drop a duplicate "0" in the list of valid
chars)
