Adding TitleIndex link to start page of Community Docs

[Peter Vander Klippe]

Can we add a link to the TitleIndex page on the front page of the
community documentation page? I was just going to do it but I saw the
comment on the FrontPage.

A lot of the wiki content is somewhat hidden and I think this would
help people see what is available on the community documentation wiki.
I know people can search but sometimes an index would help.

I'd suggest placing the link at the bottom of the "Start Here" section.

Any objections?
