Speed is about the same as before, uses slightly less memory:
```
benchmark old ns/op new ns/op delta
BenchmarkAbsURL 17302 17713 +2.38%

benchmark old allocs new allocs delta
BenchmarkAbsURL 28 24 -14.29%

benchmark old bytes new bytes delta
BenchmarkAbsURL 3422 3144 -8.12%
BenchmarkXMLAbsURL 1985 1864 -6.10%
```
Fixes#1059
Related to @bjornerik 's answer in this discussion: http://discuss.gohugo.io/t/inserting-data-from-data-file-into-content-file-newbie-question/1002/3 ... I figured I'd make myself useful and add the reference to the index function, on the go template primer page.
Also, I moved the reference links to the bottom.
A general comment: as good as these docs are, the primer at this point makes some assumptions about audience knowledge, so some might find it lacking. Once I understand better, I might make some more clarifying edits.
A couple of edits to clarify that the layout/partials folder can contain arbitrarily-named subfolders, since I found the examples using ``{{ partial "post/tag/list" . }}`` confusing. Some folders are named specifically to work a certain way with hugo, but although the examples use key functional section and taxonomy names like post and tag, it does not matter what they are called. Hopefully this will help other newbs.
The previous implementation didn't easily support the use case "I want one base template for the single pages, another for the rest".
The new lookup order is:
1. <current-path>/<template-name>-baseof.ace, e.g. list-baseof.ace
2. <current-path>/baseof.ace
3. _default/<template-name>-baseof.ace, e.g. list-baseof.ace.
4. _default/baseof.ace
One of the first things that new users have to understand is the
difference between Hugo as a web server and Hugo as a web site
generator. Issue #852 asked for documentation to make that clear.
This patch updates the overview page with that information. It will
seem repetitive to users that understand the difference. Weigh that
against the needs of those that don't.
