Issues with CommandLine exe with Mac OS

[ymark]

When executing X3ML engine using the command line exe jar, it fails when trying to read input from a folder. This happens probably because of the prefix #_ that is used for reading contents from a folder.

To overcome this issue, it is mandatory to add the folder within quotes... so the following will work as expected

java -jar x3ml-engine-exejar.jar -input "#_folder" ....

I can see two alternatives here.

1. Replace the prefix #_ with something else that will work across all OS.
2. Make the quotes mandatory. In this case, we should check if it works will all OS.
