rbx-trepanning 0.0.4 adds syntax highlighting (via coderay) and remote debugging

[Rocky Bernstein]

The major changes to rbx-trepanning on gemcutter.org are:

1. code listings and rubinius llvm listings can be syntax highlighted, if you have gems coderay and term-ansicolor installed. See 

https://github.com/rocky/rbx-trepanning/wiki/Terminal-Colors for details as to how to adjust the colors. Error messages are now in italic if highlighting; and some commands have bold section headers. The idea for section headers comes from the Reference debugger

2. Remote debugging has been added. This is the "server" command inside the debugger, or the --server and --port options on the command line; --client command-line option is used connect to an out-of-process Ruby program which is in "sever" mode.

This was added for Wayne, but I'm not sure if that's really what he was wanted.
