Upgrade gorilla/sessions to v1.2.0 

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
