[open-data-manual] New appendix to review "Barriers and Solutions to Open Data"

[Tim McNamara]

Hi all,

I spent a few hours today thinking of solutions to ~100 barriers that
a workshop last year that were posited
(http://www.flickr.com/photos/epsiplatform/5737203950/). Am mostly
complete, but wanted some feedback in the interim. I feel like a cup
of tea after ~3,000 words.

Some things I would like feedback on:

 - are the answers sound?
 - does the indent styles look okay? There a few sections that don't
use it to compare and contrast.

Regards, Tim McNamara
