/*
 * smarty_block_self_link : add a link (with A tag) to the current page on a text (passed through $content argument).
 *
 *   The generated link uses other smarty functions like query and show_sort to handle AJAX, sorting fields, and sorting icons.
 *   This block is very useful to handle table columns sorting links.
 *
 * params are the same as smarty 'query' function + some special params starting with an underscore:
 *   _sort_field : name of the field used for sorting,
 *   _sort_arg : name of the URL argument that contains the field to use for sorting. Defaults to 'sort',
 *   _ajax : if set to 'n', will force disabling AJAX even if the ajax xajax feature is enabled,	AJAX_TODO
 *   _tag : if set to 'n', will only return an URL, not the full A tag + text (AJAX and sorting features are not available in this case),
 *   _class : CSS class to use for the A tag
 *   _template : (see smarty query function 'template' param)
 *   _htmlelement : (see smarty query function 'htmlelement' param)
 *   _icon : name of the icon to use (e.g. 'page_edit', 'cross', ...)
 *   _icon_class : CSS class to use for the icon's IMG tag
 *   _menu_text : (see smarty icon function)
 *   _menu_icon : (see smarty icon function)
 *   _title : tooltip to display when the mouse is over the link. Use $content when _icon is used.
 *   _alt : alt attribute for the icon's IMG tag (use _title if _alt is not specified).
 *   _script : specify another script than the current one (this disable AJAX for this link when the current script is different).
 *   _on* : specify values of on* (e.g. onclick) HTML attributes used for javascript events
