Adds the ability to create a dynamic calendar in the first post of a topic.

Topic discussing the plugin itself can be found here: https://meta.discourse.org/t/discourse-calendar/97376

• discourse_post_event_event_will_start this DiscourseEvent will be triggered one hour before an event starts
• discourse_post_event_event_started this DiscourseEvent will be triggered when an event starts
• discourse_post_event_event_ended this DiscourseEvent will be triggered when an event ends

Custom fields can be set in plugin settings. Once added a new form will appear on event UI. These custom fields are available when a plugin event is triggered.

See an incorrect or missing holiday? Familiarize yourself with the holiday definition Syntax. Then make your updates in the vendor/holiday/definitions directory.

Generate updated holidays as follows.

cd vendor/holidays

# Generate holiday definitions
rake generate:definitions

Install the plugin and switch to the discourse root(not the plugin directory).

# Collect all holiday regions into assets/javascripts/lib/regions.js
bin/rails javascript:update_constants
