Connect 3.0

For sure

• Remove multipart middleware. Use one of the following parsers or middleware instead:
  • formidable
  • multiparty
  • connect-busboy or busboy
• Remove limit middleware
• Use raw-body for json and urlencoded body parsers (built in limit middleware and fixes #894)

Maybe

• Remove staticCache middleware
• Remove node 0.8 support
  • Remove pause utility
  • Remove any unnecessary patches in https://github.com/senchalabs/connect/blob/master/lib/patch.js
