exclude ruby-debug from 1.9.1 in Gemfile
Remove dependency on jeweler.
- Allows us to have an always-up-to-date gemspec.
- Use bundler's build/install/release rake tasks rather than jeweler's.
- One less development dependency.
- No need for a separate VERSION file.
ruby-debug19 for 1.9.2
update to aruba 0.2.0
point Gemfile to more recent aruba
add ruby-debug to Gemfile
Development env now works correctly with bundler.
