Replace DrupalWebTestCase browser with browser.inc

There is a patch for the issue...so I am going to start on this.

Items to accomplish:

• Remove all non-assertion web related code from DrupalWebTestCase.
• Provide browser instance for tests.
• Make necessary changes to browser.inc to allow all the same assertions that DrupalWebTestCase makes during requests and such.

The current code:

$this->drupalGet('node');

The new format for tests will look something like this:

$this->browser->get(url('node', array('absolute' => TRUE));

or

$this->get('node');

or

$this->browserGet('node');

That latter two being wrappers for $browser->get() and will run url() on anything passed to them, just like drupalGet(). The browser requires an absolute url.

That or we make the browser accept none-absolute in some manor.

Smart idea from webchick, leave as drupalGet() for now.

Additional dependencies:
#555374: Deal with !empty($curl_options[CURLOPT_POST]) in browser.inc
#555412: Add page listener facility to browser.inc

Very early patch.

Move to Browser module for further development.

Move to SimpleTest.

Update for tonight.

drupalGet() and drupalPost() work!

Left:
* Convert page related assertions.
* Provide drupalHeader() equivalent and related.
* Create Drupal HEAD patch to let bot run on all tests.

This is a straight re-roll after merging with HEAD.

Note that head had some AJAX additions which this patch ignores.

EDIT: browser tests still pass.

Cleaned up some minor stuff and converted a few more functions. Also implement head() in browser.inc and converted drupalHead() to use it.

Need to update/look at:
drupalGetHeaders
drupalGetHeader
assertFieldByXPath - from other box
