Hey,

tried to get vibenews v0.6.3 compiled using dub.

It kept complaining about:
source\vibenews\web.d(86): Error: no property 'prefix' for type
'vibe.http.router.URLRouter'

Obviously, since that property hasn't arrived in router.d in the version
of vibe-d that vibenews supposed to be dependent on. Which, according to
the dub.json, was v0.7.18

Problem was resolved after I did a local checkout of the latest vibe.d
(commit 7e0235673), added the local-path to dub and upgraded the
dependency to 0.7.20

How do you compile vibenews?
