Datalist polyfill: Added support for number input through the numpad, punctuation and symbols.
Correct Submodule local clone path

Previously the wet-boew-dist clone was a at the same folder level as the wet-boew.github.io clone. The gh-pages task now clones below to prevent conflicts with local dist clones.
Optimized Menu Plugin
* Recoded to cache $(document) selector for performance
* Leverage JS assignment deconstructors to reduce duplication or code in menu parts access
* Cached distinct menu parts ( grouped selectors ) in the container node to reduce jQuery selector calls

Additionaly
* Added new ":discoverable" expression since ":focusable" and ":tabable" require the elements to visible. Due to CSS3 tranisitioning some elements in the menu were in not yet visible so expression was missing them.
  ":discoverable" extends ":focusable" except that it includes elements that are hidden ( or in the case of transitioning , becoming visible )
