Added a Dejal products page

I've just added a Dejal Products page to the site.

This page serves as a quick summary of all current applications available from Dejal, plus links to the older applications and tools that I keep available for those who want them.

I imagine I'll use it for brief lists of my apps, as often appears on third-party promotion pages, e.g.:

Dejal produces Simon, a website/server monitoring tool, Time Out, a free break reminder, Caboodle, a snippet keeper, Narrator, to read stories in multiple voices, and more.
