feat: Embed the privacy policy in the app (#139 )

Instead of linking to the privacy policy embed it in the app as a string
of HTML.

The string is created with a new `markdown2resource` plugin, which
converts `PRIVACY.md` to HTML and generates a Java class with the HTML
content.

Create `PrivacyPolicyActivity` to display the HTML in a `WebView`, and
link to it from `AboutActivity`.

markdown2resource-plugin

Synopsis

Gradle plugin to convert one or more Markdown files to Java files with static constants where the Markdown has been converted to HTML. Similar (but not quite identical) to Android resources.

Example

In build.gradle:

// Install the plugin
plugins {
    id "app.pachli.plugins.markdown2resource"
}

// ...

// Configure the files to be processed
markdown2resource {
    files = [ layout.projectDirectory.file('../PRIVACY.md') ]
}

In code:

// Assume binding.privacyPolicy references a `WebView`

// The generated string constant is in the `markdownR.html` package, named
// `PRIVACY_md`. To load the content in to a WebView it must be converted to
// base64
val html = Base64.encodeToString(markdownR.html.PRIVACY_md.toByteArray(), Base64.NO_PADDING)
binding.privacyPolicy.loadData(html, "text/html", "base64")

Configuration

The markdown2resource block supports the following options.

files - a list of RegularFile in Markdown.

packageName - the package name to use for the generated resources. Default is the android.namespace of the build variant.

resourceClassName - the outer class name to use for the generated resources. Default is markdownR.

stringClassName - the inner class name to use for the generated resources. Default is html.

Tasks

The plugin creates N tasks, one for each configured build variant, named markdown2resource${variant.name.capitalized()}

For example:

You have defined debug and release build types, two tasks will be created, markdown2resourceDebug and markdown2resourceRelease.
You have defined debug and release build types and demo and full product flavours, four tasks will be created, markdown2resourceDemoDebug, markdown2resourceDemoRelease, markdown2resourceFullDebug, markdown2resourceFullRelease.
