Update satus.js limit writes to essential ones

[raszpl]

Dont save storage if new value is same as old value. The way satus works the mere act of displaying for example themes performs useless redundant writes.
Stop radio from writing on every render
Actually save just the value saved, not everything
color picker no longer writes on every render

[ImprovedTube]

(

every render
this.parentNode.storage.value = array;

*in future we might also use a color picker with one click and no OK button (could be smaller and part of the appearance section/minimap or anything)

thats a future problem :), can add variant etc when it will be needed
btw all storage functions have ability to work on multiple keys

youtube/menu/satus.js

Lines 957 to 967 in 04a604b

	satus.storage.set = function(key, value, callback) {
	var items = {},
	target = this.data;
	if (typeof key !== 'string') {
	return;
	}
	key = key.split('/').filter(function(value) {
	return value != '';
	});

but its never used and implemented in a weird way.
Even the only place where this could be used

youtube/menu/functions.js

Lines 135 to 137 in 87aa7e4

	for (var key in data) {
	satus.storage.set(key, data[key]);
	}

doesnt use this ability.
Im not a fan of function overloading, especially when its not documented. Imo it should either be

• removed because its not used at all
• moved to separate removeMany setMany getMany

Also, what is the deal with this?

youtube/menu/satus.js

Lines 884 to 885 in 04a604b

	if (typeof target === 'function') {
	return target();

is it used anywhere? what would be the usage scenario?
