Add blank document and crosslinks for work-items

[alerque]

Our charter mentions and links to this document, but it as of yet it hasn't existed. For the ease of people wanting to add items to it (see e.g. this potential work item) here is the blank template and links necessary to get to it.

If there’s a way to automatically dump a list of links to all the work-items directory’s files into the index.md file, we should do that. Otherwise, let’s just leave a link (to the directory on github.com) in the index.md (so visitors viewing the github.io page is redirected), so people don’t feel the need to update this index.md every time a new work item is added.

Oh wait, after re-reading @simoncozens’s #8 (comment), I’ve realized that I need to confirm: Is the work-items directory meant to host all the work item files at all, or just meant to be a single register page that provides links to files elsewhere?

I actually think it might be of some utility to keep a hand-written index up to date. It could have some summary information like a real title, a when and who, and other links without needing to dive into each one. I don't expect much churn because these aren't issues that will be opening and closing all the time, they are longer running projects, possibly even spawning other groups.

However as there is no harm in starting out with a link to the repository directory I've gone ahead and added that.

I was initially envisioning it would be a register page, but it might be useful to have a file list too. In most cases they wouldn't be the actual work, just the proposal to start the work and the plan for how it would be done. Those proposals might fit in a section-per-proposal, but a file-per-proposal could work too. And the latter would make it easier to see who was involved in which proposals from Git history.

Per this comment I'll look into what we can convince GitHub's stripped down Jekyll to do for us as far as an automatic index from a directory and perhaps meta data. In the mean time I think this can be merged as-is to provide a directory for such charter PR's to start working in.
