Showing options for content body.
Data entered in content parameters will show up in text area as formatted content body.
For collection and list types, can now add additional elements; collections can be minimized; text area made bigger for easier viewing.
Adding in @dgc-wh's code to send content in requests for which content has been given. 'content' has replaced 'requestBody' in this commit.
Setup 'config.rb' for Compass use. Modifying the Sass file will be easier with Compass available.
Updated 'style.scss' to generate the current style.css file correctly.
Content parameters now use nested lists instead of nested tables. It was
easier to figure out how to style nested lists than nested tables.  All of
the capabilities there were present in nested tables are present with nested
lists.
Adding 'list-only' type for generating a single array in the content text
area instead of the usual (javascript) object. Stylesheet updated as
well.
Adding missing 'plus' image for adding collections.
Updating things for content parameters patch.
Updated stylesheet with style.scss, probably need to add style.css changes from master to it.
Minor updates to content_parameters.js, docs.js, and working on documentation for content_parameters.js in a docco style.
