Subject: [PATCH] * Removed the unnecessary function replace_escaped_spaces
 (never used) * 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.)
