wpColorPicker does not respect `hide` option

[tollmanz]

wpColorPicker() appears to support the hide option by listing it in the options property. When iris is initialized, the hide value is hardcoded and not taken from the options array. wpColorPicker() should respect the hide value passed to it.

To reproduce, initialize a wpColorPicker() with the following code:

$input.wpColorPicker({
  hide: true
});

Notice that the color picker is in the closed state. It should be opened when hide is passed.

Added a patch to respect the hide option.

In looking at this some more, I see that there is code that attempts to trigger the click event on the "toggle" element, effectively opening the color picker; however, it is tricky to consistently trigger such an event on a hidden element, which was a requirement in my case.

Respecting the hide option by passing it to the iris() function still seems to be a valid solution.

Patch still applies.

@azaozz: Care to take a look at the viability of this?

This looks like a typo, the hide option is set in the defaults but never used.

I see no reason any of the options passed to iris should be hard-coded. They should all respect the params passed to wpColorPicker. As such, I've created a new ticket: https://core.trac.wordpress.org/ticket/30182
