- function get_mimetypes_array() now contains also information about filetype groups and language strings - use 'smart' human-readable mimetype description - never determine filetype group based on filetype icon image! remove function mimeinfo_from_icon() - get rid of class filetype_parser and file lib/filestorage/file_types.mm, replaced with functions file_get_typegroup(), file_extension_in_typegroup() and file_mimetype_in_typegroup() - support multiple icon sizes, not only 16 and 32 - retrieve filetype icon only using proper functions file_..._icon() from lib/filelib.php throughout the code - increase size of repository thumbnails to 90 and icons to 24 (will take effect when new icons exist)
