Make a way of caching gists completely

[nicferrier]

First off, this is a brilliant brilliant tool. I really love it.

Second, I'd really like a way to just download all my gists and keep them locally (in my .emacs.d somewhere ideally).

I might have a go at hacking it together myself but I thought I'd create the issue here anyway to get your thoughts on the idea.

I'm not sure what would be the right approach. I see mostly 2:

• have a filesystem-based version of the caching code, and probably use some .dir-locals.el file to keep pushing modifications at save time
• or go the full git way, and actually clone the gists, but then one would have to handle them manually for updates

Maybe both options should be provided, actually...

I prefer the latter. I think in memory and full git clone would be what I was interested in.
