Add commands for email templates

[ColinFrick]

There should be similar commands for working with email templates:

• email:download - Download all email templates to a directory
• email:upload - Upload all email templates from a directory
• email:watch - Watch a directory for changes

Handling for HTML / Text templates and localization must be implemented.

For consideration:

• email:test - Send a test email through FusionAuth to the given email address
• Should the base information of the email (Name, Default Subject, From Email, Default from name) also be exported / modifiable?

This would be cool. I'd suggest that you have the following folder structure under the TMP dir:

emails/
   default/
      9dd63c26-5c18-4f9e-aa03-d414b05e529f/
         html_body.html
         text_body.txt
         name.txt
         default_subject.txt
         from_email.txt
         default_from_name.txt
      3bd2a8c6-513f-4fc3-908f-7cb68e743893/
   en/
   de/

So the pattern is email/locale/template_id and all the files needed to patch the email object are stored in that directory.

Because the localized templates are contained in the email object itself wouldn't it make more sense to structure the directory like this?

emails/
    9dd63c26-5c18-4f9e-aa03-d414b05e529f/
        name.txt
        from_email.txt
        default/
            html_body.txt
            text_body.txt
            from_name.txt
            subject.txt
        af_NA/
            html_body.txt
            text_body.txt
            from_name.txt
            subject.txt
        de/

Ah, good point. Makes sense.
