* Refactor/remove websockets functionality for relaying opstats from server with direct polling by client
* Implement delta responses initially introduced in #91 to reduce bandwidth
since 'to' be now be templated a user can configure a message to send to the subreddit the action is being processed from using `to: 'r/{{item.subreddit}}'`
* Add top-level 'actionSummary' template variable that renders a markdown list of action results
* Add individual action result/data, in the same structure as rules, under the top-level 'actions' template variable
* Implement interfaces for template parts
* Refactor Action constructor to take an object for runtime options (cleaner, more extensible)
* Refactor subreddit resource and snoowraputils content rendering and organization to use objects of optional data rather than required arguments
* Make almost all data optional and only parse/render if included
* Move rule results parsing/formatting into own function
* Refactor footer render to use renderContent (DRY)
* Add some requested template data #104
* {{item.subreddit}} #87
* {{check}} #87
* Updated templating documentation
* Create self/link submissions, no reddit media (upload) yet
* Submission can use user modifiers (nsfw, spoiler) and mod modifiers (sticky, distinguish, lock)
* Can create submission in current subreddit (default) or arbitrary subreddit defined in configuration (targets)
* Can create multiple submissions by defining multiple targets
* Check for no/null guest data during invite creation/usage for both client and server side
* Add instances tab on invite page
* Replace instance select on invite page with query string usage
* Redirect from status page to auth helper when instance has no bots
* Rename to Guest since this is more accurate of a description -- "mod" is confusing since user doesn't have any actual mod power
* Add guests as an option to invite creation and display on invite page
It makes more sense for the CM instance that will actually have a bot added to it to own the invite for that bot.
* (BC) Move Invite into server entity mappings and rename to BotInvite
* Add guests and initialConfig (future use)
* BC -- Existing invites need to have instance defined to be used
* BC -- Cache-based invite storage has been REMOVED
* BC -- Removed inviteMaxAge config property (for now)
* Add SubredditInvite entity for future use
* Force/implement server (api) having a defined friendly name. This is used to determine which invites in a DB belong to which server instance
* If not defined in config it is generated at random and then written to config
* Refactor how invites are retrieved and parsed client-side -- CRUD using server api
* BC -- Invite URL structure has changed from ?invite=id to /invite/id...
* Added better UI for migration redirect
* Show all reachable instances in redirect page header
* Error page also shows reachable instances in page header
