Title: nginx: adds option to compile with image filter module

nginx ngx_http_image_filter_module is a filter that transforms images in JPEG, GIF, and PNG formats. This module is not built by default. This change enables the optional compilation of nginx with image filtering support using the --with-image-filter when performing a brew install. This change is necessary to optionally support image filtering because nginx does not support dynamically loaded modules.
