Twitter Bootstrap Compatibility

Wrap inactive elements in span (current page, prev/next buttons at ends
of range).
More Flexible Paginator

Zurb foundation expects pagination links wrapped in anchor tags <a>
even on the current page. This seems like a safer approach.
Framework-compatible breadcrumbs

Add new options to getCrumbList to allow it to be used to make
breadcrumbs in Twitter Bootstrap or Zurb foundation. Follows the model

Only try to use CakeErrorController if AppController exists.

AppController.

Fixes #3850
Fix issues with getting Xml as SimpleXmlElement and invalid Xml.

Fixes #3855
do not translate error message in test case
This fixes an issue where attempting to use "!=" in a condition with an array with only a single element generates invalid SQL.

Example:
$condition['Model.id !='] = array(1, 2); //Generates Model.id NOT IN (1, 2) as expected
$condition['Model.id !='] = array(1); //Generates Model.id != = (1) which is invalid SQL

Patch will cause the above to generate Model.id != (1);
