EOW Changes

Brought normalize.min.css into whatever.css through @import
Changed sub-title
added [tabindex] for div.btn
Added more button variants
Added more helper classes (.sm, .lg, .xl, .input-block, .input-item)
that will eventually get shorter names
Added github project URL to CSS
Removed most CSS comments as many were obvious. Will revisit.
Removed bulky selectors for input buttons. Inputs now need class .btn
to have style.
Button contents now vertically centered
Added obvious button colors for :hover and :active.
Removed display inline, block, and inline-block helper classes as it's
best to define with custom CSS
Added .text-left-stacked and .text-right-stacked helper classes (may
not stay based on lack of use)
Re-introduced button borders to show overwritable rules.
Merge branch 'gh-pages' of https://github.com/jephrei/whatever into gh-pages
