This seems to be incompatible with the RHEL6 compiler.

Added non-virtual clone() interface with a virtual private doClone()
method to Workspace and derived classes. Workspaces that had a clone()
method before were adapted to have a common interface everywhere. In
cases where there was no clone() method previously we simply throw an
error for now, until this new functionality is implemented.

Some tests/mocks had to be adapted since there there is a pure virtual
doClone() in all abstract classes.

Do to smart pointer incompatibilities (mainly due to old boost versions)
we had do extract the raw pointer from the unique_ptr returned by clone
and put it into a boost::shared_ptr manually, in some cases. See also
issue 12949.

Workspace is polymorphic, so in general we do not want any public copy
or assignment. In some cases this required moving the user defined copy
constructor out of the public area, in other cases it meant adding it in
the protected section, to avoid auto-generation by the compiler.

Note that we make the copy constructor protected and not private. This
is in view of the upcoming introduction of a clone() method, which will
need to call the copy constructor of the base class.

Before I convert this to a vector of workspaces, I notice that the same variable name WS is used both for local variables, and member variables. This is utterly stupid and bound to cause problems in the future, so i'm fixing the naming here first.

Since we have put PeakShape in Geometry, SpecialCoordinateSystem must be moved to the Kernel package out of API.
