Removed "parent" project

Aggregated parent projects should not be used in a multimodule project
if it is built at the same time as the project.
Moved tycho-platform-configuration to the parent
Added name and description to the modules
Added ignore for maven-enforce-plugin in m2e

Removed the warning "maven-enforcer-plugin (goal "enforce") is
ignored by m2e"
Changed version to 4.0.1-SNAPSHOT

That way there's a consistent version throughout the multiple modules.
