Update developer and organization data

See #311.

Hm, do we actually need that information in the config file? There is also a section for contributors in the documentation, which we are not using so far. The developers section is meant for committers. But that whole distinction of committers and contributors is kind of obsolete with Git. The actual overview of contributors is at https://github.com/metafacture/metafacture-core/graphs/contributors. Maybe we can simply remove the developers section? And the top-level organization too, since the idea is that this is a community project. That would leave only the header change and the update of the ciManagement.

The information is used to build e.g. 'https://repo1.maven.org/maven2/org/metafacture/metamorph/5.2.0/metamorph-5.2.0.pom'. I don't know if it is used by anyone or of it is of any importance. But at least the organization may make sense - it is defined as

Configures the organization for the publication represented by this POM.

(https://docs.gradle.org/current/dsl/org.gradle.api.publish.maven.MavenPom.html#org.gradle.api.publish.maven.MavenPom:organization(org.gradle.api.Action)

and may make sense by taking dedicated responsibility bound to an organization (which may, as you note, handed over to an other organization) building some kind of trust regarding a future development.
What do you think?

Looking at the way the organization is used e.g. here, I think it would make sense to point to the GitHub organization with something like name Metafacture & url https://github.com/metafacture

Removed developers section and point to github organization.
