* cargo fmt & clippy

* Skip anchor checking for URL with prefix in config

* Let toc is visable through Page & Section variables in templates

* Removed the current toc variable from page & section

Links that start with a scheme (e.g., `tel:18008675309`) inadvertently
had a URL prefix prepended. Previously, only `mailto:` was handled, but
given the sheer number of [registered URI schemes][uri-schemes], a loose
pattern matcher is used to detect schemes instead.

External links, as identified by the renderer, are now limited to `http`
and `https` schemes.

Fixes #747 and fixes #816.

Closes #813

Presently when you `^C` in `zola serve` it is painted with the same
color as the previous message. This PR always ensures to reset the color
in colorize, before writing the newline.

Hello !
I'm proposing my ZOLA blog to fill your examples list.

I'm very satisfied by ZOLA, thanks you for creating all this.

Updated the copyright year in the docs template to reflect the new year.

- "/templates" section is gone upstream

Add ZEIT Now support

EXAMPLES: Add ozkriff.games

v0.9.0

* Improved the grammar of README.md.

Also made stylistic changes.

* Corrected a typo.

* Bump pulldown_cmark to version 0.6.0

* Rename headers to headings

* Add anchor existant checking to link_checker component

* Oops, forgot some changes

* Drop scraper dependency and rework tests

* Handle name attributes

The access to translations is not straightforward and requires checks if
language and key exists. It is better to forbit direct access to
attribute and provide method - `get_translation()` - that will handle
all details of key translations.

Remove unit tests that use direct access and test only public method.

* fix the issue of generating the search index for multiple language

* updat docs for generating the search index for multiple language

* fix failed tests

* add tests for the search index of multiple language

Add method get_translation(lang, key) into Config struct that retrieves
translated term from parsed configuration or error when either
desired language or key is missing.

Use the new method in Trans struct implementing global Tera function
trans().

Add unit test to cover both happy and error path for translation
retrieval in both config and templates crate.

* Fix the issue when checking the changes of multiple language section

Closes #790

Added instructions on how to publish to <username>.github.io or <org>.github.io by changing the publishing branch in the repo to `master`. This should work for any type of GitHub publishing, including custom domains.
