Removed the center align tag from the logo.
Sadly Github does not support `<center>`. As of Jan 2017, because github markdown doesn't support HTML/CSS at the moment, It does allow <br>!

Update the URL of the docs badge to include it from inch-ci.org instead of inch-pages.github.io (the former being the successor of the Inch Pages project).
http://shields.io/ provides many standardized badges for OSS. The PNG versions provided by Shields are similar to the images currently used, but the SVG versions added here are more legible on high pixel density displays.
Inch Pages themselves provide a SVG badge, so use it!
