Also make some tweaks:
- Merge SerializeAction::$include and
SerializeAction::$includeAvailable into a keyed boolean array
- Set defaults for SerializeAction::$limit and $limitMax
- Rename SerializeAction::$sortAvailable to $sortFields
- In order to be consistent with the Ember/LESS naming scheme, renamed
Flarum\Web to Flarum\Forum.
- Moved common classes into Flarum\Support so that Flarum\Admin doesn’t
depend on Flarum\Forum. Also moved Actor into Flarum\Support as it
doesn’t belong in the domain.
