add a way to pre-select checkboxes and radio buttons

[ralyodio]

    <div class="field">
        <label for="type">Employee Type:</label>
        <ul class="list">
        <% for (let type of types) { %>
            <li>
                <label>
                    %= await ctx.radioButtonTag('type', { value: type.value, checked: gig.type === type.value})
                    <%= type.label %>
                </label>
            </li>
        <% } %>
        </ul>
    </div>

This would be the ideal API imo, where checked attribute would be set if statement is true.

Same goes for checkboxes vs. radio buttons.

currently do this as a work around:

 <input type="radio" <%= gig.type === type.value ? 'checked' : ''%> value="<%= type.value %>">
