Updating theme to 1.11.0

[mattstratton]

A few slightly important changes to pay attention to in this release - specifically, we now resize speaker images to square, with a minimum resolution of 300px by 300px, so you might need to update your speaker images if they are smaller than that.

Also, we have moved the map below the city icons, in order to keep the branding of the map, but push the content up above the fold!

You can now also include content in your program files, besides the auto-generated program.
