[Vala] libsoup cookie example

[bsquared <bwcode4u gmail com>]

I put together a small sample that demonstrates using libsoup to access
couchdb (could be any server) with cookie based authentication.  I would
like to make it available to others.

Should I add it to the current libsoup examples, or create a new page?

Thank you.
