how to remove deprecation warnings for link_to_function

Since rails 3.2.4 the link_to_function is effectively deprecated (again). Everything keeps on working, but when running my specs I got a horseload of deprecation warnings. I know the optimal/recommended way is to use unobtrusive javascript, but the quickest way to fix this is really easy. Just perform the following translation:

    # before 
    link_to_function icon_tag('close.png'), '$(this).parent().hide()', :title => t('actions.close'), :class => 'close' 

    # after 
    link_to icon_tag('close.png'), '#', :onclick => '$(this).parent().hide()', :title => t('actions.close'), :class => 'close' 

Dead-easy :) In the next refactoring I will remove all onclick blocks and replace them with unobtrusive javascript. But for now I got rid of the deprecation warnings :)
