Prettier for .properties Files

Adds support to Prettier (v2.3 and later) for .properties files.
To use, install it:

``
npm install --save-dev prettier-plugin-properties
`

and then add it to your Prettier plugin configuration.

Configuration

In addition to the default options, two additional options are available:

$3

Escape with \u all non-Latin-1 characters, to allow safely encoding output as ISO-8859-1.

| Default | CLI Override | API Override |
| ------- | --------------------- | ------------------------- |
| false | --escape-non-latin1 | escapeNonLatin1: |

$3

Set the separator to use between a property key and its value.

Valid options:

" " | ":" | "=" | ": " | "= " | " : " | " = "

| Default | CLI Override | API Override |
| ------- | ------------------------- | ----------------------- |
| " = " | --key-separator "" | keySeparator: "" |

$3

To apply separate Prettier configuration for different file types,
you may use configuration overrides.
For example:

`json
{
"overrides": [
{
"files": "*.properties",
"options": {
"printWidth": 0
}
}
]
}
