Bumping Version to 0.13-DEV
Making partials context optional for compatibility with template.

If not provided, context is nil.
Taxonomies can now be provided as a single string value if there is only one in frontmatter (tag = "val" vs tag = ["val"])
A small fix and update to the multilingual example

Enclose `{{ .Content }}` with a `{{ if .IsPage }}` test to avoid
the "Content is not a field of struct type *hugolib.Node" error.
Thanks to @spf13 for the tip!  Fixes #366.

Also update example to Hugo v0.12 conventions:
- Convert config.yaml to config.toml to follow what
  `hugo new site /path/to/site` generates
- Rename layouts/chrome to layouts/partials
- Convert `template` calls to `partial` calls
- Add .gitignore to ignore the `public` directory
- Add README.md with pointers to discussions in issues
  to help bring newcomers up to speed with this multilingual example
More proofreading and minor revisions to Hugo docs

Among the various changes, most instances of

    {{ template "partials/FILE.html" . }}

were changed to

    {{ partial "FILE.html" . }}

Also, in main.go, change "2013" to "2013-14".
Go back to lowercase slugs. Also, use MakePathToLower in TestMakeToLower.

go fmt
add Name to File, which is the filename minus the extension
Add Node.Site.Pages to all nodes and ensure all pages from the site exist in the list before processing shortcodes.

Node.Site.Recent is not really just recent pages, but all pages, so I figured it was better to add a new parameter with a more informative name.

I also changed the code slightly so that all pages are added to the list of pages before we start rendering shortcodes... this way you can use a shortcode to refer to another page.  Previosuly, this had been broken, because the list ofg pages would not be fully populated while the shortcodes were being processed.  The code that does this is not reading from disk or doing any rendering, so it shouldn't take any more time to do.
Fix typo in Archetypes documentation.

Archetype was spelled archtype in one of the headers.
