A working backtrace for linux

[David Bryant]

Ok,

I've added -L--export-dynamic to dmd.conf and done a copy/modify of 
DefaultTraceInfo from runtime.d to include demangling and catch certain 
signals. My backtraces now look gorgeous under Linux.

I've attached the source for the updated module.

Thanks,
Dave

I'll sort out demangling as well, it's just a bit more work.  I like the stack trace code provided, but it uses a lot of modules that aren't available to druntime so it would be difficult to use directly.
