switched jquery to no conflict mode because of conflict with prototype.js from magento
refactored common.js:
- fixed bug with access to ajaxHomeUrl inside $.get()
- replaced $ with jQuery to avoid conflicts with prototype
- added check for aoe static cookie prefix in the document.cookie to speed up replaceCookieContent()
- added more events to replaceAjaxBlocks() method (each block now triggers own before/after replace events)
- added possibility to call replaceAjaxBlocks() method with custom array of block names and some refactoring related
- cleaned up beforebodyend.phtml (moved code to blocks class methods)
