* Added an extra widget configuration option, that allows the user to choose large, small or no icons (defaults to "no icons", keeping the original plugin behavior)
* Added a frontend.css file to the ./assets/css/ folder for styling the icons display (each file name was wrapped in an additional <div> tag, to help with the positioning of the icons)
* Added filetype icon images to ./assets/images/
* Some tweaks in the i18n functions
* Added Brazilian Portuguese (pt_BR) translation files
