Give a warning if version of libgmx has changed

[GoogleCodeExporter]

There are unpredictable segfaults when the loaded version of libgmx differs 
from the one compiled with (binary incompatibility).

CsgApplication should drop a warning at rumtime if the version differs.

Add the check in all gmx topology/trajectory reader/writers. (warning will 
occur several times, but better this way)

Get gmx version with:

grompp -h 2>&1 | /bin/sed -n 
's/^.*\(VERSION[[:space:]]*[^[:space:]]*\)[[:space:]]*.*$/x\1x/p' > 
gmx_version.h

It is better to create a small cpp program using GMX_CFLAGS and GMX_LIBS, which 
prints the version string. (in case grompp differs from libgmx used for 
compiling.)
Failback to UNDEFINED if execution of this program fails.
