tab_width as an instance variable

[stephen@…]

I really like Markdown with TabWidth?=2. However, I'd rather not maintain my own fork of the codebase just to change the class-eval-time constant.

So I pulled it out into an instance variable. This had a few side effects, most notably that a few regular expressions that depended on TabWidth? could not be class level anymore either.

I've attached a patch.

Oh. I should do a unit test too. But I've been fighting with this enough for this morning. Perhaps I'll do it later. Prod me if its important.

This would be easy to wrap in the changes necessary for #34.
