jpass.properties is ignored when the application is started from other directory where the jar file is

Related details from #19:

In windows I start the jar from a batch file that is in the same directory as the jar and the jpass.properties file.
In linux I had a bash file in a different location and in the bash file uses variables:
${java11Home}/bin/java -jar ${jpassDir}/${jarFile} ${jpassDir}/${jpFile}
Here the ${jpassDir} specifies the directory that contains the jar, the jpass.properties and the encrypted *.jpass file containing the password entries. I did this mainly because I was comparing different versions of jpass builds (different resulting jars) and run with different versions of the JDK, each configuration run with its own bash file. (In Windows I only have the JDK 11.0.9 installed).

Now I noticed that running jpass this way the jpass.properties is ignored. I took more notice because I changed the ui.theme.dark.mode.enabled=true to see if the FlatDarkLaf was really used with your fix. On Windows I saw the dark look and feel, but in Linux I didn't.
However, when I run in a console in the same directory where jar, jpass.properties and *.jpass file are in then the dark theme is enabled, which looks cool, by the way.
