ADD: Added config option $default_icc_file which is used for image magick.

* You can greatly improve CMYK thumbnail rendering this way, for example, by
  using a sRGB profile instead of an sRGB color space.
* If you don't like the extra profile, you can even define something like:
  $default_icc_profile='my-sRGB-profile.icc +profile *' which gives the
  visual benefits of the sRGB profile without any extra space requirements.

CHG: ip_matches() now supports regexp.

* If your IP wildcard starts with '!' it is considered a regular expression,
  just like the auto_login plugin does it.
