Migrated to Cakefile from Makefile+runner. Got outdated action working for the first time.
Added status action

- Also remove redundant joe include
- No longer link bal-util
Added html2jade and html2coffee to skip tests as their dependencies aren't that maintained. Correctly named the .travis.yml file.
Removed travis.yml file, should be the responsibility of the plugins
Merge branch 'master' into docpad-6.x
Exchange changes: Added Bevry and Startup Hostel websites. Updated DocPad website license.
Better cloning
