Log Message:
-----------
add multiple extension dirs support, needed eg. in eclipse where lib/ext/ and
lib/plus/ are separate folders. might be usable in the future to place each
extension in their own folder.
use by giving multiple -plug-in-directory params eg. -plug-in-directory
"lib\plus" -plug-in-directory "lib\ext"
