Support for extracting shared library companion objects

Hi,

It would be nice if BridJ would not only extract the shared libraries, but also there companion files (files on which the library could depend). This would allow shipping/extracting additional debug symbols (pdb or gdb files) in the jar which would then be picked-up automatically by debugging tools.

For example extract both lib/win32/myLibrary.dll and lib/win32/myLibrary.pdb.

I'm willing to take a stab at this feature, but at first glance it would require some large changes in the Platform class. Any ideas or opinions on this?
