[TextMate] feature request: separators

[Caio Chassot]

I want to be able to insert separators in the project drawer. For 
example, when I create a rails project, I have the following roots:
- controllers
- models
- helpers
- views
- javascripts
- stylesheets
- rails

I want to use separators to be able to view them as follows:
- controllers
- models
- helpers
- views
   -----
- javascripts
- stylesheets
   -----
- rails

I guess I could use groups or something, but I prefer to avoid nesting, 
otherwise I'd just do it with the rails dir and nothing more.
