Add For Attribute to Stand Alone Label Component

[bdlb77]

What is the current behaviour?
When using the label component from class Label < Matestack::Ui::Core::Component::Static;end , no options[:for] is defined in the class. This makes it so the <label> tag cannot find the correct <input>, <meter>, or corresponding HTML element that it is intended for.

label for: 'meter', text: "Meter Label"
meter id: 'meter', value: 0.4

returns

<label>Meter Label</label>
<meter id="meter" value="0.4"></meter>

If the current behaviour is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem. Your bug might get fixed faster if we can run your code and it doesn't have extra dependencies. Add a link to a sample repo and/or any relevant code below:
