Updates script file to conditionally include commands
Updates script file to conditionally include commands

Some commands require things such as the application container file to
be in place. In such cases, the script fails due to autoloading and/or
missing container.

The script now does the following:

- Checks to see if the PWD contains a vendor directory. If so, it does a
  `chdir(getcwd()`, and then a `require 'vendor/autoload.php`.
- It creates a default list of always-available commands.
- If a `config/container.php` file exists, it adds the `handler:create`
  and `action:create` commands.
