extension:install composer packages

[tomjanssens]

If a package name (vendor/package) is passed to the extension:install command, install it using Composer

@stevenrombauts the above commit was started at the Timble Workshop. On the train you said there might be other relevant tickets relating to composer?

[stevenrombauts]

@yiendos I was referring to tickets #21 and #28. But this ticket is still unrelated to those right now: here we just want to be able to install components by package name instead of local directory.

For example: joomla extension:install joomlatools/joomla-todo should recognise the name as a Composer package (format foo/bar) and instead of calling the bootstrapper and the installer logic, it should do a composer require <package name>.

@yiendos Does this require any more work?

[yiendos]

hmmm @stevenrombauts I honestly can't remember the state of this ticket. I can jump back in and refresh myself with the code

[stevenrombauts]

Thanks @yiendos, nothing urgent, it looks like this code is basically finished so no reason not to include it in the upcoming 1.5 release then - unless it needs a lot more work.

[stevenrombauts]

Working like a charm, @yiendos. Thanks!
