Mr. Guid 0.2.8 does not require local copies of
scripts for remote debugging anymore. The scripts
are transferred to the client automatically as
needed. (Therefore no file arguments need to be
passed to mr_guid)

Note: Instability in the Windows version is still
possible (and probably exists). I would appreciate
any help on this issue.

Smaller changes:
- Eliminated global variables from gdebug.rb

Mitchell's Ruby GUI Debugger (Mr. Guid) is a simple
cross-platform Ruby GUI debugger written in Ruby
using the Ruby/Gtk2 bindings for GTK+. It is only
meant to be a debugger, not an editor or IDE.
