Added the ability to ban and unban users. Improved the installation instructions. Changed the collation of the tables from utf8_general_ci to utf8mb4_general_ci. Changed the group ID order. Custom pages are now templates rather than little snippets being inserted into a template. Changed the collation of the driver to utf8mb4_general_ci. Added a default_group config setting. Ban flag is overwritten for admins and super mods.
