jQuery 1.11.1, removed jquery-form dependency, makefile optimizations

- raised jQuery version to 1.11.1
- removed dependency on jquery-form and use standard jquery api instead
- optimize makefile to run with npm < 1.4.x and > 1.4.x, support cli arguments ``debug=true`` and ``verbose=true`` for a little more verbose test output.

regarding jQuery 1.11.1:
- we may still have/want to remove dependency on jquery.event.drag and jquery.event.drop and use standard HTML5 events instead.
- one test in patterns-formunloadalert is skipped, because the karma/phantomjs/jquery combination is complaining about: "Some of your tests did a full page reload!"
