Use iipc-web-commons consistently as the project name

This project should be named consistently. If the github repository is called "iipc-web-commons", it can only cause confusion to make the artifact name "commons-web", since that will be the name of the distribution jar and/or tar.gz. Having a third name, "OpenWayback Web Commons", in the readme, is even more confusing. 

The most important thing, imho, is that the names be consistent. So if it has to be "commons-web", let's make it commons-web everywhere. Likewise if it has to be "OpenWayback Web Commons". But I think "iipc-web-commons" is the most appropriate name.

"commons-web" doesn't make sense to me in English, "web-commons" does. The only reason to reverse that ordering is if it's a subproject of something called "commons". And "commons-web" invites confusion with the http://commons.apache.org/ subprojects. Also commons-web is very generic sounding, it could be a lot of things, so I think qualifying it with "iipc" is appropriate.

I don't particularly like "OpenWayback Web Commons" either, because the library is used for more than just openwayback.

But the most important thing in my mind is that the names be consistent.
