Adjustments to embed templates

renamed styles, adjusted the 'powered by' footer so that it works,
added methods to return absolute URLs rather than relative.
Fixes table styles
Adding title and description to the table view (it looks better with the description)
Simplifying the Custom View options

Reduced the available options and removed links to documentation and
examples. There is still some work to do to get the detailed view to
make more sense.
