YADE Standalone Client should consider directories for patches and for user .jar files

Current Situation

• The YADE Standalone Client Setup considers two directories that are added to the class path:
  • <yade_home>/lib/3rd-party
  • <yade_home>/lib/sos
• The YADE patches are installed in the <java_home>/lib/3rd-party directory (based on class loading priority).
  • Among other things, this approach makes it difficult to maintain an overview of the current patch status of a YADE installation.

Desired Behaviour

• A separate directory should be used to install patches.
• A separate directory should be used to install user individual jar files.
