* 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.)
