Merge pull request #16 from terbolous/master

Improvements to survey.htmlMade the survey.html agnostic to protocol used, previously
the iframe was hardcoded with a http:// link and this breaks when
visiting the site over https.

Also set the iframe height to 2000px and enabled scrollbars, this is
to allow longer sides to show properly without the need of having a
really long page for all other pages

  Improvements to survey.html
