Added file-cache-case-fold-search and file-cache-assoc-function variables

(file-cache-minibuffer-complete): Use file-cache-assoc-function.
Use file-cache-case-fold-search variable
(file-cache-add-file): Use file-cache-assoc-function
(file-cache-delete-file): likewise
(file-cache-directory-name): likewise
(file-cache-debug-read-from-minibuffer): likewise

;; ADDING FILES TO THE CACHE:

;; Use the following functions to add items to the file cache:
;;
;;
;; * `file-cache-add-file': Adds a single file to the cache
;;
;; * `file-cache-add-file-list': Adds a list of files to the cache
;;
;; The following functions use the regular expressions in
;; `file-cache-delete-regexps' to eliminate unwanted files:
;;
;;
;; * `file-cache-add-directory': Adds the files in a directory to the
;; cache. You can also specify a regular expression to match the files
