patch to fix pgadmin1.8.4 build on Solaris 10.

[Mayuresh Nirhali <Mayuresh(dot)Nirhali(at)Sun(dot)COM>]

Hello,

While building pgadmin 1.8.4 on Solaris 10, I encountered following error.

"./debugger/dbgPgConn.cpp", line 97: Error: INADDR_NONE is not defined.
gmake[2]: *** [dbgPgConn.o] Error 1

This seems to be a known problem with Solaris10.
I prepared a patch based on how the same issue is worked around in
'pgadmin/db/pgConn.cpp' and it is attached here.

please feel free to comment/review the same.

cheers
Mayuresh
