[CRA-283]
Reading input gravity files. Only one input file with all data (5 columns), removed input of location coordinates.

Added ModelGravityStatic and ModelGravityDynamic.
[CRA-283],[CRA-285]
Initial implementation of gravimetric inversion. Not finished, not completely tested.
Fixed conflicts after merge.

CRA-598 Do not write background model in depth when time-to-depth mapping
does not exist. This is applicable when we use the velocity from seismic
inversion to make the mapping. In these cases, the background model will
currently not be written to disk. This is unfortunate.
