AboutContent class

An about box. This is a dialog box with the application's icon, name, version number, and copyright, plus a button to show licenses for software used by the application.

To show an AboutContent, use showAboutPage.

If the application has a Drawer, the AboutPageListTile widget can make the process of showing an about dialog simpler.

The AboutContent shown by showAboutPage includes a button that calls showLicensePage.

The licenses shown on the MarkdownPage are those returned by the LicenseRegistry API, which can be used to add more licenses to the list.
