Project pages

[dsheets]

Based on the site-merge branch, this introduces simple project pages with future-focused diffs (e.g. "after 0.4.0"). The indexes are updated to link to both most recent version and the project and the packages are updated to link to projects via the header (which now contains a full version).

Should be fixed, now.

Can you rebase to master (to pick the Travis scripts)? Thanks?

Are you still working on that branch or can I start hacking some styling / CSS issues?

[dsheets]

You are free to develop off of this branch. I've started another feature branch for the PRs and one for the docs.

Closing this one as #139 has been merged
