[idea] Setting to configure word regex.

[trusktr]

For example, I am using this, and would like to match the regex that vim-mode uses for * and #. Possibly would be nice to add option to match vim-mode's regex, or to allow a custom regex.

Yeah, I have this idea from start, this package is port of my vim-quickhl to Atom. Original vim version have regex option and static pattern(always highlighted keywords without manual operation).

It's good to have, but I have many thing to do in other project, so if someone sent PR I'll welcome to look into. Or else, I can implement if I have time and want some refreshment. Thanks for suggestion.
