Allow show/hiding options on condition

[jeffreyvr]

Allows you to show an option if a condition is met.

Select::make(__('Image alignment'), 'image_alignment', [
    'left' => __('Left'),
    'right' => __('Right'),
    'center' => __('Center'),
])->condition('image'),

How it works: simply passes the string you fill in onto a wrapper div with the x-show attribute.
