This gets rid of the gorilla/context dependency, which might have been
causing a memory leak.
We noticed some serious memory leakage on Write.as that seemed to point
to this library. One heap snapshot:

With the help of these articles, we tracked it down to this dependency,
and upgraded the library, which seems to have completely fixed the issue
so far:

This should fix#133
this adds basic support for importing files as blog posts.
.txt and .md are supported at this time and the
collection is selectable, defaulting to draft.
if a collection is specified the post is federated.
This upgrades the library to v2, which lets you specify that GOMAXPROCs
should always be the max number of CPUs -- and then sets it to that.
One side effect of this is that images are no longer listed in sitemaps.
I'm somehow at a loss on how to build and append the images array we
need, with the library's latest changes.
Fixes#86
