[Users] Patch for TwoPunctures

Hi,

The attached patch fixes a couple of minor problems in the TwoPunctures thorn:

1) When the bare masses are not given as parameters (give_bare_mass=no), they are calculated at double precision, but the par_m_plus and par_m_minus parameters are then only set at single precision.

2) When the bare masses have been calculated, they are printed to stdout. In some cases, the initial guess for the bare mass is printed rather than the final calculated bare mass.
