/**
* Creates a link tag of the given +name+ using an URL created by the set of +options+. See the valid options in
* the documentation for ActionController::Base*url_for. It's also possible to pass a string instead of an array of options
* to get a link tag that just points without consideration. If null is passed as a name, the link itself will become
* the name.
*
* The html_options has three special features. One for creating javascript confirm alerts where if you pass
* 'confirm' => 'Are you sure?', the link will be guarded with a JS popup asking that question.
* If the user accepts, the link is processed, otherwise not.
*
* Another for creating a popup window, which is done by either passing 'popup' with true or the options of the window in
* Javascript form.
*
* And a third for making the link do a POST request (instead of the regular GET) through a dynamically added form
* element that is instantly submitted. Note that if the user has turned off Javascript, the request will fall back on
* the GET. So its your responsibility to determine what the action should be once it arrives at the controller.
* The POST form is turned on by passing 'post' as true. Note, it's not possible to use POST requests and popup targets
* at the same time (an exception will be thrown).
*
* Examples:
* $url->link_to('Delete this page', array('action' => 'destroy', 'id' => $page->id ), array('confirm' => 'Are you sure?'));
* $url->link_to('Help', array('action' => 'help'), array('popup' => true));
* $url->link_to('Busy loop', array('action' => 'busy'), array('popup' => ['new_window', 'height=300,width=600']));
* $url->link_to('Destroy account', array('action' => 'destroy'), array('confirm' => 'Are you sure?'), array('post' => true));
