first pass, dispense with old buttons and move to AddThis buttons
- add AddThis smartlayers for follow-me on twitter/facebook
- add AddThis sharing buttons (actually that was last update, but this time
  shorten them down to as-recommended in homework)
- add AddThis follow buttons in the contact section

TODO:
- change all text to use new FileClerk name
- get fileclerk.co domain (or similar)
- tidy/consistency in style
Merge branch 'master' into develop
- tidy up naming -- now the only references to wherearemyfiles are in S3
- increased contact section font
- properly aligned seperate addthis_toolbox divs by splitting them into id=
- tidy up new follow/contact section spacing
- changed color on Smart Layers, it now integrates beautifully!
- About link and Contact link now work via id= tags, not sections

TODO:
- padding so that the About link aligns correctly
- padding so that the Contact section puts contacts at the top/middle
