Social media meta tags

Based on http://moz.com/blog/meta-data-templates-123
I’m not sure if the image strings in the meta tags get also hashed via
Sebs magic build script (http://www.nightlybuild.io/img/logo.png does
not exist on the server but with .hash prefix) Can somebody confirm
this?

Touch icons and iOS 7 web app meta tags

Touch icons for normal and retina resolution with iOS 7 icon sizes for
iPhone and iPad, meta tags to enable iOS full screen mode, title and
translucent status bar.

This commit also depends on the build script adjustment by Sebastian
because the PNG touch images are referenced in the meta tags and need
to be suffixed with hash string.
Fix up doubled dist config in copy task.

Looks like a merge conflict hasn’t been solved
properly so there were two dist config objects
in the code.
Also: Whitespace clean-up.
Use PNG logo instead of SVG.

This fixes #18.

Also: Small code-style clean-ups.
Add non-retina logo, switch placeholder image.
Added Steffen to the list of speakers in the console
Added hash save logo for social icons
