added many promised features which were not available yet due to hard wired setups.

It's now possible to run B.D with higher degree of freedom than SS fits.
Bulge & Disk can have different degrees of freedom in non-obvious parameters (x,y,ar,PA)
If DOF of fit parameter in B.D fit is 1, Galapagos now makes sure that input values are homogeneous, so it doesn't keep the offsets between bands (from SS fit).
