Add a new GemBump Event

• Added a new on: gem_bump event which will remind you when a gem inside your
  Gemfile.lock snapshot gets updated to a specific version.

  # TODO(on: gem_bump('rails', '6.1'), to: '...')

Multiple dispatchers

[1.1.0] - 2019-09-06

Fixed

• Fixed the SmartTodo cop to add an offense in case a SmartTodo has a wrong event.

  # Bad
  #
  # TODO(on '2019-08-08')

Added

• SmartTodo will now use the fallback channel in case a todo has a channel
  assignee that doesn't exist.

• Added a new Output dispatcher which will just output the expired event.
  By default SmartTodo will now output expired todo in the terminal instead
  of not running at all.

  Users should now pass a --dispatcher to the CLI to let SmartTodo through
  which dispatcher the message should be send.

    bin/smart_todo --dispatcher 'slack'

  For backward compatibility reasons, the dispacher used will be Slack, in
  case you have the ENABLE_SMART_TODO environment set. This will be removed
  in the next major version.

Enforce assignee on SmartTodo

The SmartTodo cop will now add a violation if a SmartTodo has no assignee:

# Bad
#
# TODO(on: date('2019-08-08'))
