always seems to want outgoing_token defined in config

It gives this error at runtime if it's not defined:

/usr/local/lib/ruby/gems/2.3.0/gems/slackbotsy-0.4.2/lib/slackbotsy/bot.rb:28:in parse_outgoing_tokens': undefined methodto_set' for nil:NilClass (NoMethodError)
Did you mean? to_s
from /usr/local/lib/ruby/gems/2.3.0/gems/slackbotsy-0.4.2/lib/slackbotsy/bot.rb:15:in initialize' from ./standuptime.rb:17:innew'
from ./standuptime.rb:17:in `

'

I'm using the web api for slack, so this shouldn't be needed...only the api token is needed.

Dupe of #11.
