[Doc-SIG] Simplified table syntax proposals (reStructuredText)

[David Goodger]

I've added some new, simplified but limited, alternative table syntax
proposals (http://docutils.sf.net/spec/rst/problems.html#tables,
alternatives 3, 4, and 5), incorporating an idea from Simon Hefti.
There's a better example of alternative 3 in the notes.txt file
(http://docutils.sf.net/spec/notes.html#bugs).

Could people please take a look at these alternatives and tell me what
they think?  Thank you.
