Merge pull request #419 from jglodek/patch-2

Fixed sequence of a and p tags.
updated change log for #419
Fixed #420: Xing provider references VkProviderSettings
Use named loggers for all providers logging
Use an aggregator project

This doesn't change the way the samples projects are defined (hence you can copy
paste them out of the master project and they will still work I kept the unused
plugins.sbt files in the samples on purpose)

However it should make developers life easier as they won't have to remove the
ivy cache, republish a snapshot locally and rerun the sample project to test
changed. A developer can now use `project scalaDemo` or `project javaDemo` to
activate the wanted project then run. Any change in the sample project or in the
module-code project will trigger an application reload effectively making
modifications available immediately.
