dlpoly topology reader (c++ part) uses hard-coded fortran function name

[GoogleCodeExporter]

When testing VOTCA on AIX, I realized that xlf uses a different name mangling 
scheme than gfortran/ifc hence compiling fails at a linking stage as the 
fortran functions are not found.

cmake provides a way to detect the mangling scheme automatically.

I guess it was one of the routines/functions that I left without the C-name
specified when binding F to C (for testing).
Thanks for fixing it.

The problem is basically that gfortran mangles a fortran function ffunction() 
-> ffunction_(), while xlf does ffunction() -> FFUNCTION__().

I added auto-detection for that in cmake.
