Martin Gräßlin d25c465211 Move layer functionality to AbstractClient
Merges together the code from ShellClient and Client and removes the
starting differences. Long term it's better to have only one
implementation to prevent diversions in the implementation.

As it doesn't match exactly protected virtual methods are called
which allow more specific implementations for a certain aspect of the
layer resolving.
