initial wizard mods to use of 'data-step' instead of 'data-target' and ids. also changing default behavior to pick starting step from 'active' class, if possible. also modifying 'disablePreviousStep' option to be set via 'data-restricted="previous"' or via instantiation config
added addSteps function to wizard
Merge branch '3.0.0-wip' into wizard-updates
added removeSteps function to wizard. also syncSteps, but that is not really intended for external use
addSteps function now a lot cleaner, utilizes removeSteps function
reverting dev back to normal state. also moving updated wizard html to index page
Merge pull request #426 from ExactTarget/wizard-updates
