Missing: the development web server. I don't think that sees much use,
we can convert it to http.server when/if someone ever needs it on a box
without python2.

Warm thanks to all that have participated making devicedetect.vcl what
it is.

However, as this file was not maintained, the later contributors
got no glory at all. Doesn't seem fair.

Fix X-UA-Device-force cookie

Not required

Change resp.response to resp.reason as this is passed to vcl_synth
Change set of  resp.response to resp.http.response (varnish 4)
Setting resp.status before using resp.reason resets resp.reason to "OK" and results in A-UA-Device-force cooking being set to "OK". Swap ordering to avoid this.
