These are code style and minor syntax changes. So nothing in functionality should be changed.
This PR is the 2nd in a series.
This is a cleanup of the following folders:
/administrator/components/com_categories
/administrator/components/com_checkin
/administrator/components/com_config
administrator/templates/hathor/html/com_categories
administrator/templates/hathor/html/com_checkin
/administrator/templates/hathor/html/com_config
Testing instructions
Check if all the views of these components still function as expected.
