inlet profile from file is not initialized from config.cfg

[bigfooted]

When SU2 creates an inlet profile file, the values in the file are set to 0.0, expect for the vertex coordinates. The values used to be initialized from MARKER_INLET in the config file. Any particular reason this initialization disappeared? I propose to add this again, and also to add a line to inlet.dat with the names of the variables in the columns so it's easier for users to see what's in the columns.

implementation result:

NMARK= 2
MARKER_TAG= inlet_air
NROW=32
NCOL=8

Sounds good so long as backwards compatibility is kept and the names for the columns and default values are passed into CMarkerProfileReaderFVM in a way that does not require it to do anything problem-specific.

yes, it works with and without the additional column information.
