Title: Fix Paperclip's io_adapters to properly sanitize original_filename

The ":" is a special character in file paths passed to ImageMagick's
"identify" command. Even though Cocaine (and everything else in paperclip)
escapes special characters correctly, we need to strip it out of filenames to
ensure identify (and probably other ImageMagick commands) can run correctly.
