bash ain't no js yo! :squirrel:

there are no commas in bash arrays (or so i learned). zsh and bash prints them to stdout.
the way randomness is generated, will always cause "ace" or whatever the
first word in the array is to be omitted. see empty lines when running:

for i in {1..1000}; do ./superb.sh; done | sort

remove the duplicates of "dazzling" and "flawless" - see sindresorhus/superb#3.
propose "prodigious" and include "stupendous" proposed by @tamagokun to
achieve 100 words. ;)
