Core: erroneous wrapper scripts

Hello,

I'm using Jalopy-b9

jalopy.sh (and preferences.sh) can only be started
by using the full pathname to the script-file.

So only :
> /usr/local/bin/jalopy.sh

will work.
If you have /usr/local/bin in your PATH than the following
wont work :
> jalopy.sh
A NoClassDefFoundError is being fhrown then.

A solution to this is to change the following line in
jalopy.sh (and preferences.sh) :

DIRLIBS=../lib/*.jar
into
DIRLIBS=${0%/*}/../lib/*.jar

This is tested on linux and on windows (cygwin)
