Twig variable dump improvements

[brandonkelly]

Description

Adds a new dump() function, which outputs a variable(s) via Craft::dump(). It replaces the dump() function provided by Twig’s Debug extension, and doesn’t require Dev Mode to be active. To maintain consistency with the original, the new one supports outputting multiple variables at once by passing them as separate arguments, and will default to outputting the entire context array if no arguments are provided.

{{ dump(foo, bar, baz) }}
{{ dump() }} → context array

The {% dd %} tag has also been updated to no longer require a variable, in which case the entire context array will be output.

{% dd foo %}
{% dd %} → context array

Passing multiple values to {% dd %} is not supported, as the application will exit before we could loop around to the second. If you want to do that, you’d have to pass them as a hash:

{% dd {foo: foo, bar: bar} %}
