update for h5bp

[sams]

consistent with h5bp v4

• update html conditional comments
• update styles (spliting into main.css & normalize.css)
• update scripts (rename libs to vendor, rename script.js to main.js)
• centralize HtmlHelper css & script calls in layout
• update jquery & modernizr
• remove AutoView & ThemedAuto View

Does the original H5BP project still have modernizr enabled by default? I don't actually think it's used that much and am starting to think we should leave it commented out?

yes h5bp does have include modernizr. commenting it out is no biggie, I do think it is extremely useful
