Release Notes

## Enhancements:

* Support the POSIX convention for cluster multiple options. For example, `-ixd` is treated the same as `-i -x -d`.
* @bjorg: support SingleOrNoValue notation. `--option[:value]`
* New type: `Pager`. Provides a simple interaction model for displaying console output in a pager.
* Display help text using the `less` pager on macOS/Linux.
* Make suggestions when invalid options or commands are used, but there is a valid one that is similar. (Thanks to @MadbHatter for doing the initial work on this.)
* Add support for subcommand aliases. Commands can be given multiple names.
* Obsolete the constructor of `[Subcommand]` which takes a string.
* Infer subcommand names from the type name
* @lvermeulen: Sort subcommands by name in help text. This can be disabled with `DefaultHelpTextGenerator.SortCommandsByName`.
* @jcaillon: Add API for `UnrecognizedCommandParsingException` which includes suggestions for similar options or commands.
* @TheConstructor: add CommandLineApplication.GetValidationResult()

## Bugs fixed:

* Duplicate subcommand names used to cause undefined behavior. Now, attempting to add a duplicate subcommand name or aliases will cause the library to throw before the app can execute.
* Fix bug in subcommand name inference. When not specified, the subcommand always matched the entry assembly name. In this update, this convention only applies to the parent command.
* Add generic overloads of `.IsRequired()` for `CommandOption<T>` and `CommandArgument<T>`.
* @handcraftedsource: handled nested HelpOptions (fixes #86 - InvalidOperationException when multiple help options were defined)
