Suggestion: Allow asking `configatron.something?`

[DannyBen]

It would be nice if configatron.param? will simply be (conceptually-) aliased to !! configatron.param

# Allow asking `configatron.something?`
configatron.force = false
p configatron.force  ? "forced" : "not forced"
p configatron.force? ? "forced" : "not forced"
# => "not forced"
#    "forced" (but expected "not forced")
