[#19,data/api][s]: local .csv url for downloading the primary resource.
[refactor,data/show][s]: switch data grid display to run off new local csv url rather than remote.

This means we are no longer specific to github and can run off any data package.
[vendor/recline][s]: remove local recline and slickgrid as we will use submodule.
[vendor/recline][xs]: add in recline as a submodule.
[#40,data/show][m]: support for displaying custom data "views" (e.g. graph, grid etc) via spec in datapackage.json.
