Adding check for gfortran version.

gfortran 4.4
The 'mrepl' mode in waves did not really work... FIXED
Added a "viceversa" option to 'mrepl' and 'repl'.
The connectivity entries must now be named on the "add" command. All other commands will interpret either the connectivity number or the corresponding name.
Allowed additional names for "qsig"=="qdamp", "qalp"=="qbroad" and for "delta"=="corrquadratic" "gamma"=="corrlinear".
Replaced explicit comparison of parameters in 'set' by a string_compare to allow more flexibility/readability of macros.
Needed a complementary name for the connectivity lists to work with mmc.
A line
Si   1./3.,  2./3., 0.00,  0.1
did not work properly. Fixed
Dynamic allocations for new molecule types caused by the Symmetry
mode repl,new
had been forgotten. FIXED
The 'Select' part of 'save' used the wrong flag to signal that these atoms were old and that no new atom type should be created. FIXED
the include file arpa/inet.h had been missing, which caused the strange integer to pointer without cast error message and the crashes related to memcpy FIXED
The setup in diffev.f90 did not include the call to cmdline_args! FIXED
Allowed the string representing a macro parameter to be of length 180 instead 80.
make did not find the system mpi.mod . Can be fixed by changing the MPI_LIBRARIES and MPI_INCLUDE_PATH variables to MPI_Fortran_LIBRAARIES and MPI_Fortran_INCLUDE_PATH
run_mpi could only handle directory names with length 80, Changed to handle directory names up to 240 characters long.
Added stdlib.h and string.h for stricter adherence definition of malloc, strncpy, strlen and memcpy
Added many individual return codes, ensured that not domain name server is needed for "localhost" or "127.0.0.1"
Modified error output to allow longer lines,
Added socket error messages
Added MPI related error messages to diffev
Added a variable to reduce socket output
Added socket related error checks
Canceled output for Socket "Ready"
coupled socket output to prompt status
trivial change of lpara from real to integer in do_show_generic
changed getcwd to function and related "USE IFPORT"
