Added possibility to change forces from ActionAtomistic
Added fit to template
POSITION CV

It works. However, it should be used after FIT_TO_TEMPLATE.
I think it should not be merged until a test that enforces
this has been implemented.
Fixed arbitrary phase in MDS

I added a few lines to set to a predictably value the
arbitrary phase in the eigenvectors used for MDS.
This should make the runs more reproducible.

Fix arbitrary phase in eigenvectors in diagMat

As suggested by Gareth, I moved the fix in arbitrary phase from
ClassicalMDS to diagMat
Fixed regtest after last commit
Merge branch 'fix-mds' into v2.1
Removed timestamp from manual

This will allow me to simplify the update of online manual
(before I needed to remove with a scripts the timestamps
a posteriori to avoid too many differences at every update)
Merge branch 'v2.0' into v2.1
Movingrestraint: add kappa as a component

this should close #99
@davidebr can you double check?
gromacs 5.0: patch

it should works, but more tests are needed
CHANGEs: updated
CS2BACKBONE: fixed problem with chemical shifts output files
Removed some regtest

NUMERICAL_DERIVATIVES is always difficult to reproduce on different machines
Added warning on POSITION
Merge branch 'fix-98' into v2.1
Added SCALED_COMPONENTS to POSITION
