Added RDIE to cached term
Removed divisions from cached version
Corrected k_psi torsion correction constant
removed old parameters
Changed location of parameters
Moved E_psi correction to dihedral terms
Updated terminal charges to parameters from Sandro
Fixed RDIE coulomb screening and charge on CTERM carbonyl carbon, and torsion parameters with E_psi correction
Fixed a few parameter bugs, and code passes tri peptide testset.
Merge pull request #3 from andersx/master

Fixed minor parameterbugs, and code yields correct energies (i.e. code is ready!).
