Support for ->required() on the label within a form group

[clemblanco]

By intercepting the required($conditional) function here we will add automatically the control-label-required CSS class to the <label> HTML element.

This way you are able to use CSS to style the <label> HTML element however you want, you can even use pseudo-elements to add an asterisk:

label.control-label-required:after {
    content: " *";
}

Obviously we wont interfere with Form Builder and we'll call the required() function defined within adamwathan/form no matter what. The CSS class will just be added conditionally.

Any chance this goes into a release? Would like to avoid having to use dev-master if possible.
