dnebauerandJeremy Ruston bfd09133de Add howto for changing highlight languages (#3674)
* Create howto.tid

Howto explains customising the languages supported by the highlight plugin. This involves:

* Using the highlight.js download page to get a zip archive containing the files for a highlight.js server which supports a set of languages selected by the user
* Replacing the highlight plugin's `highlight.pack.js` file with the `highlight.pack.js` file from the downloaded archive

* Update plugin.info

Add howto.

title: $:/plugins/tiddlywiki/highlight/readme

This plugin provides syntax highlighting of code blocks using v8.8.0 of [[highlight.js|https://github.com/isagalaev/highlight.js]] from Ivan Sagalaev.

! Usage

When the plugin is installed it automatically applies highlighting to all codeblocks defined with triple backticks or with the CodeBlockWidget.

The language can optionally be specified after the opening triple braces:

<$codeblock code="""```css
 * { margin: 0; padding: 0; } /* micro reset */

html { font-size: 62.5%; }
body { font-size: 14px; font-size: 1.4rem; } /* =14px */
h1   { font-size: 24px; font-size: 2.4rem; } /* =24px */
```"""/>

If no language is specified highlight.js will attempt to automatically detect the language.

! Built-in Language Brushes

The plugin includes support for the following languages (referred to as "brushes" by highlight.js):

* apache
* bash
* coffeescript
* cpp
* cs
* css
* diff
* http
* ini
* java
* javascript
* json
* makefile
* markdown
* nginx
* objectivec
* perl
* php
* python
* ruby
* sql
* xml

You can also specify the language as a MIME content type (eg `text/html` or `text/css`). The mapping is accomplished via mapping tiddlers whose titles start with `$:/config/HighlightPlugin/TypeMappings/`.
