changed: winix 'upload' function is a file manager now

we're using an jquery upload plugin
added:   Item struct has new rows: hash, hash_type, file_size, sort_index
added:   css mount parameter
         you can specify css files there, and javascript wysiwyg editors
         (ckeditor, tinymce) can make use of it
changed: post parsers can parse post variables with the same name
         (a postfix is added in such a case)
added:   common_dir parameter to the config
         this is a path to common directory (directory with common static files)
         it is needed to the 'css' mount parameter
