* Provides a simple "jump menu".
*
* A jump menu is a select box and an optional 'go' button which can be removed
* if javascript is in use. Each item is keyed to the href that the button
* should go to. With javascript, the page is immediately redirected. Without
* javascript, the form is submitted and a drupal_goto() is given.

/**
* Generate a jump menu form.
*
* This can either be used with drupal_get_form() or directly added to a
* form. The button provides its own submit handler so by default, other
* submit handlers will not be called.
*
* One note: Do not use #tree = TRUE or it will be unable to find the
* proper value.
*
* @code
* ctools_include('jump-menu');
* $output = drupal_get_form('ctools_jump_menu', $targets, $options);
* @endcode
*
* @param $select
* An array suitable for use as the #options. The keys will be the direct
* URLs that will be jumped to, so you absolutely must encode these using
* url() in order for them to work reliably.
*
* @param $options
* $options may be an array with the following options:
* - 'title': The text to display for the #title attribute.
* - 'description': The text to display for the #description attribute.
* - 'default_value': The text to display for the #default_value attribute.
* - 'hide': If TRUE the go button will be set to hide via javascript and
* will submit on change.
* - 'button': The text to display on the button.
* - 'image': If set, an image button will be used instead, and the image
* set to this.
* - 'inline': If set to TRUE (default) the display will be forced inline.
