new option "Mesh.SaveWithoutOrphans" to prune orphan entities (entities not connected to any highest dimensional entity in a model) from MSH4 files (cf. #2129)

only set entity color during occ sync if the entity has no color; this should lead to more intuitive behavior (cf. #2125)

fix for #2111: since we accept free form BDF files without continuation markers, the number of nodes of CPENTA elements cannot be computed without reading the next line

was not properly initialised. Now each individual character is copied
into the Fortran string.

bug: fixes short-circuit expressions

See merge request !474

Short-circuit expressions are not supported in Fortran
removed them and replaced them with explicit conditionals.

Improving the Fortran API

See merge request !470

Already was writing out the tags for Physical Surfaces so made sense
to add output the tags for Physical Volumes in the same manner.
