Attempting to wrangle data from calendar json files
Improved parsing of irc.Event to respond to user

irc.Event struct now parsed to expose username who pinged the bot so
that the response includes the users name. eg: "ropes: <meetingtime>"
Global vars for event data, changing to use chans

Initially thought it would be a good idea to use global variables for
containing event data.  Going to switch to using concurrency and
channels just to learn them as well as files being updated will show up
in the bot without a restart.
Concurrent event file loading added

Concurrently parsing json event files and passing data back through
channels.  Attempting to add tests by the type issues caused by channel
declarations cause issues when only able to pass type 'interface{}'.
JSON unmarshalling issues breaking struct
