[Xymon] xymond option --merge-clientlocal and clientupdate

Hi Henrik,

If xymond is started with the "--merge-clientlocal" option and returns more than one clientversion: lines then clientupdate on xymon client not works properly.

////According to the rule "host before class before os" the following modificationof xymonclient.sh would be correct:

• SERVERVERSION=grep "^clientversion:" $LOGFETCHCFG | cut -d: -f2

• SERVERVERSION=grep "^clientversion:" $LOGFETCHCFG | cut -d: -f2 | head -n1

In the xymond manpage must be also "--merge-clientlocal" instead of "--merge-clientconfig".

Thanks Alex
