/TH/SURF : compatibility with EBCS

Description of the changes

Time History is generated through T01, T02, ... files
There are now 6 output parameters available for surface time history when defining option /TH/SURF :

• AREA (surface area),
• MASSFLOW (mass flow) <- updated
• V (mean velocity),
• P (mean pressure),
• A (specific to LOADP & PLOAD),
• MASS (cumulated mass) <- new

What's new :

• EBCS are now compatible with /TH/SURF : surface identifiers related to /EBCS options are now available in time histories
• MASSFLOW was renamed into MASS (it has output so far cumulated mass instead of mass flow)
• MASS is introduced : it had been output so far with MASSFLOW keyword instead
• number of channels harcoded in th_surf_mod (single location in source code) : INTEGER,PARAMETER :: TH_SURF_NUM_CHANNELS = 6
• FSAVSURF renamed TH_SURF%CHANNELS and defined in th_surf_mod

conflict resolving led to compiler error. I am going to update.
