Help tag rendered by #control_group method

[carloslopes]

This way is possible to render help and error messages for standalone control_groups.

Example:

<%= f.control_group :skill_level, label: { text: 'Skill' }, help: 'This is important!' do %>
  <%= f.radio_button :skill_level, 0, label: 'Novice', inline: true %>
  <%= f.radio_button :skill_level, 1, label: 'Intermediate', inline: true %>
  <%= f.radio_button :skill_level, 2, label: 'Advanced', inline: true %>
<% end %>

The commit 4aae6c3 fixed a strange bug that was happening when i was trying to set an help to a standalone control-group

I couldn't reproduce the bug on tests, it was really weird

Sorry I haven't had a chance to look at this yet. I've been swamped with a new product launch at work. Will get a chance in the next few days...
