Pbb init and index links

pbb now adds a link to the index page to every page on the blog. The link doubles as the blog title, and the index page now has the heading “All posts”.

It has learned a new command as well: pbb init initializes a blog in an empty Git repository. It

• creates the source branch,
• adds the artifacts directory to the .gitignore file,
• prompts for the blog title (which is no longer hardcoded),
• creates the includes and images directories,
• creates a header file with the blog title for the link mentioned above, and
• creates a dummy post.

I’m thinking of renaming the images directory to something like assets or static and have pandoc look for it with the --resource-path option; that’d save some typing when writing posts.
