[TxMt] “Reformat Comment” command for Ruby bundle

This command overrides reformat paragraph in the comment.line.number- sign.ruby scope. Here is the description given by rubywrap.rb:

# RubyWrap is a word wrapper utility designed for ruby scripts. It should, # however work for any programming language which uses an initial prefix for # comments (see --prefix). RubyWrap correctly handles indented comments, # indented text within comments, header comments, and many forms of lists. It # will also pass through code without change and detabify.

Any interest in adding this to the Ruby bundle?

rubywrap.rb goes in Ruby.tmbundle/Support/bin.
