Improve assets

[EnriqueVidal]

We use assets (uploads) to render pages with photos (for now, possibly other type of content in the future), but we currently do not provide the possibility to delete already uploaded assets, plus we depend on flash to do the upload, we need to improve this by:

• Use backbone.js to create a nicer interface that will allow us to add/delete
• Try uploading files using an iframe instead of flash (not-key but would definitely remove the CMS dependency on flash in 100%)
• Abstract the asset's and have different type of objects inherit from them like (photo, video, etc) and create a polymorphic association on asset to relate it to other objects like (page), etc.
• If possible put the whole asset functionality in an external page.

We should start by changing from paperclip to carrierwave as mentioned in #22

agree

Wordpress has a similar system for handling those kinds of media when you add them to a webpage.

I think the polymorphic assoc is definitely the way to go.
