Rebuild wysihtml5 implementation and layout

 * Remove bootstrap style navbar implementatation which utilizes ul/li
 elements. Instead, I use the existing anchor elements and use the
 display: inline-block css property to add styling as needed.
   * The result is cleaner, more concise html.
 * Rebuilt the CSS stylesheet from scratch.
   * Class and ID names are more descriptive and used correctly.
   * Selector names 'dasherized'
   * Utilized Mixins and Variables.
   * These changes shortened the stylesheet from 117 to 72 lines.
 * The 'Title' submission section uses the default H1 styles. This is
 achieved by nesting the textarea inside an H1 element.
   * Added 'Title' label back in.
 * Remove placeholder text for both 'Title' and 'Body' submission fields
 * Page displays correctly on Chrome, Firefox, Safari. Not sure about IE
