v1 Prep for sprint

[haustraliaer]

Just some quick notes from looking over the current state of the prototype.

The following functionality should (if possible) be implemented before we go away to the country to finalise version 1 of the app:

• Setup the concept of Pages (move sections inside pages).
• Probably remove the pre-scaffolded sections / pages.
• Ability to destroy a page, or section in the relevant list (with a button).
• Use actual subdomains for each brandguide (within pow + on heroku).
• Section for uploading images to insert into markdown.
• Custom thumbnail for asset groups (defaults to asset png file, but can be overridden).
• Create long url public zips
• Send email with link to zip url
• Some way of auto inserting webfonts... (might have to work this out at the sprint)

I've done a few already, but if you've got time please extract these and post as individual issues so they can be assigned and labelled.
