More improvements regarding tbl(7) options.

* Treat "allbox" as an alias for "box" for now.
* Parse and ignore the GNU tbl "nowarn" option.
* For separation, allow spaces, tabs, and commas only.
* Mark eqn(7) within tbl(7) as unsupported.
* Simplify the option table.
* Improve and sort documentation.
