Adds a Crowdstrike code name generator

This should add a new command to slackrbot called "crowdstrike". It can be issued with no parameters or with a country name after it. If a country is provided it will try to make a code name that fits that country.

ex: "artie crowdstrike"
ex: "artie crowdstrike china"
ex: "artie crowdstrike north korea"
