Fix tinymce lang file path to define EDITOR_LANGUAGE
Let formatSize return a specific size

Extend NumberHelper->formatSize(): now we can specify a specific unit.
For instance: formatSize(1024) returns '1.00 KB',
but formatSize(1024, 'bytes') returns '1,024 bytes'
Use NumberHelper->formatSize when formatting file sizes
