Simple fixes

Add org.openide.options-based options back; the editor still requires it. This should restore tab-settings persistence to Ruby files. Also hook up the bracket-completion option such that if you turn it off in the options dialog, bracket completion stops completing symbols.

- Update the comment action such that it now toggles comments rather than just adding or subtracting (like the Java editor just did).
- Remove old-style indentation hooks to the IDE and implement the new editor indentation API. This is necessary to support RHTML indentation (which itself is not working properly yet).
- Fix delete word such that it performs camel-case deletion like the Java editor
- Update unit tests
- Some other code cleanup

Fix auto-completion which was hardcoded on the gsf side instead of on the ruby side (which meant it didn't accurately block auto completion on ranges, in strings and a couple of other problems). Also fix scenario where it pops up on things like numbers (typing in pi, 3.14, slowly would invoke code completion).
Also fix unit tests for bracket completion now that 108889 is mostly fixed.

The bracket completer api should be passing the JTextComponent rather than just the Caret such that the bracket completer can be more flexible (such as looking at selection positions)

Remove old editor settings; probably incompatible with new and no longer seem to be necessary

Ruby: Prepare for providing Ruby hints (parse job listener delegates to the language plugin at the right time etc.)
