We need a USER_DIR to install BiglyBT globally on Linux

[sergiomb2]

Regarding issue #2157 , I noticed that -Djava.library.path= and -Dazureus.install.path are always equal but can be different , let install plugins on homedir while main jar is installed java.library.path , fix my packaging problem .

My only suggestion (bikeshedders, assemble!) would be to go with something other than INSTALL_DIR, if the example path is going to be pointed at the user's $HOME/.biglybt directory. That's not really any kind of "install" dir. CONFIG_DIR or SETTINGS_DIR or USER_PLUGINS_DIR or something like that strikes me as more descriptive, if that's where it's expected to point.

And if that's not where it's expected to point (like, say, it's pointing instead to a shared plugins path), then I'd still go with PLUGINS_DIR or something like that. PROGRAM_DIR and INSTALL_DIR sound like the exact same thing, to me.

indeed, USER_PLUGINS_DIR is more intuitive , with USER_PLUGINS_DIR we may install plugins in our home directory and have biglybt installed on system, /usr/share/java/biglybt .

thanks for the suggestion

I changed the commit message to: [1] and the commit also already uses USER_PLUGINS_DIR as suggested.

We need a USER_PLUGINS_DIR

so that BiglyBT can be installed in the PROGRAM_DIR without write permission for the user, and the user can store their    
own plugins in their USER_PLUGINS_DIR.

so that BiglyBT can be installed in the PROGRAM_DIR, where users do not have write permissions, while users can store their plugins and configuration in the USER_DIR.
