 In the general case, a file extension may represent more than one MIME
 type. Currently, file extensions are married to a single MIME.

 Specifically, let's look at the case of the "ico" file extension.
 Officially, the MIME type for this file should be
 "image/vnd.microsoft.icon". Unofficially, "image/x-icon" along with many
 others are usable.

 The solution to this problem is extremely simple.

 First, allow key => value pairs in the exhaustive MIME list located in
 wp_get_mime_types to be arrays so we can account for cases such as ico.

 Second, add the proper handling for this change in wp_check_filetype. The
 way I have written it should not interfere with existing uses of this
 function (as they were all passing strings and now can pass a string or
 array).
