Adds jekyll-get plugin

[JJediny]

Optionally Plugin to get dataset.json and data.json from another instance of JKAN to cache and potentially use on another site

See #77 for context

Thanks for the PR! This sounds really interesting but I'm a little confused about how you'd use it. I assume it's something you'd need to do on the command line since github pages doesn't support plugins, but would you mind elaborating a bit? or do you have an example you're using somewhere?

Fascinating! Let's see if it takes off.

@timwis my taught on this is that someone could run jekyll build to pull in a json file either from a JKAN and/or CKAN API or agency.gov/data.json... and push the file created local into the git repo

While gh-pages doesn't support plugins its not needed as the json is committed as a new file for use in the site. One could potential use this to mash up datasets remotely host with those on their JKAN... or maybe offer a search functionality that includes those remote datasets along with those on JKAN.

If I'm understanding correctly, I really like this idea!

Slight aside for my context:

My city currently has a few competing data portals, and we're building community one to boot. I think I can perhaps convince one of the portals to use JKAN. The other is eventually migrating to CKAN. It would be nice if our community one could pull in /data.json files from each so that all our datasets show in one place, without requiring massive amounts of bureaucratic collaboration :)
