remove the TargetSpace parameter of the Cosserat energy class -- Cosserat materials only make sense with RigidBodyMotion values

[[Imported from SVN: r7418]]

It will implement the energy of the elastic Cosserat modell
for continua and shells proposed by Patrizio Neff.  So far
it is only a copy of the harmonic energy, though.

using the ideas of Patrizio Neff.

In particular, this code should handle real 3d continua, as well
as Neff-style Cosserat shells.

This initial commit only adds a lot of infrastructure.

Compute the local corrections in local coordinates on the tangent bundle now, instead of using the embedding in the surrounding space

[[Imported from SVN: r5985]]

For this now the TangentVector class of S^n has only n components,
while the EmbeddedTangentVector class still has n+1.
The code around it needs to be fixed accordingly.

now works on a per-element basis and has been moved to the local rod assembler.
That way, it has lost most of its 1d-ness.  In the future, it will be usable
for other problems as well.

The class 'Configuration' is now called 'RigidBodyMotion', and can be parametrized by the space dimension
