Add option to get_search_form() to not include current search query in the form

[joelhardi]

This is a minor enhancement that adds a new option to the argument array of get_search_form(). The new option would enable the user/theme developer to easily output a search form either with (this is the current function) or without the current search query prepopulated in the <input> field of the search form. Right now there is no easy way to include an always-empty search form in a template. For example, the user might prefer to have a regular/empty search box in a sidebar or other secondary location.

In the patch I've added a 'show_query' option that defaults to true.

So when the template calls get_search_form(array('show_query' => false)) then the search form is output with an empty <input> field. (And get_search_query() is not called.)

There is no change in function when a template calls get_search_form() and doesn't include this new option, so there's no impact on existing templates.

Thanks for considering this enhancement!
