Added @if attribute to the "puts" tag. Now when the if attribute is present, it will output the value of the variable defined in the @value_for attribute if and only if the condition is true. The @if attribute follows the same syntax as the "if" attribute.
Extended the <r:puts /> tag by allowing to output simple text through the @text attribute. This can be useful when adding flexibility to snippets and generating conditional html.
