resolves #3051 drop the options attribute

- don't store the options attribute on the block once the options are parsed
- only store options as individual attributes (e.g., header-option)
- add an options method on AbstractNode to retrieve the set of option names
- store partial-option as empty string instead of true
- reference low-level option attribute internally
