Images Caching

Images are usually redirected through EWIKI_SCRIPT_BINARY+, and ewiki
tries to save them inside the database as with uploaded images. So
most of the facts from the previous paragraph apply to this function
too.

You must enable this feature with EWIKI_IMAGE_CACHING+, it is shipped
disabled currently.
Adding a ?nocache to the image URL disables this feature for just one
specific image, if _IMAGE_CACHING was otherwise enabled.

Images are downscaled to fit the maximum defined size in
EWIKI_IMAGE_MAXSIZE+ (bytes) if the PHP libgd extension is available
(else dropped and then always redirecting clients which request
those image).

You cannot modify the README file, but anyhow any ideas or suggestion should as usually get filed on BugReports, UserSuggestions or even better the README.Discussion.
