* Changed all instances of replace_spaces to the actual function call (removing the silly wrapper function replace_spaces) * Added a collapseable folder list for left_main.php * Added the option for it under Options -> Folders (Sorry that I didn't do this in smaller commits that only did one or two of the above actions.)
