Issue 45 resources broken

This PR relates to the missing SVGs (application and the landing page) when viewed in IE. I have switched them over to pngs for this version of TM. It addresses issues #12 and #45 . It affects all pages in the application (the navbars have been changed) and the landing pages:

landing-page-index.html
landing-page-about.html
landing-page-features.html

Is it possible to have them as svg's in browsers/devices that support them when we do the flare version?
