SOAP authentication fails on WP with CCRM 4.3+

During SOAP authentication against Wordpress 3.5.1+ and CCRM 4.3+ you get the following error:

Call to undefined function wp_authenticate()

This error is thrown in CRM_Utils_System_WordPress::authenticate (line 367 in CCRM 4.3.4, line 364 in CCRM 4.3.0)

$user = wp_authenticate($name, $password);

Here's a proposed fix (line #s are for CCRM 4.3.0):

1. edit <your_wp_location>/wp-content/plugins/civicrm/civicrm/CRM/Utils/SoapServer.php to load bootstrap when in WordPress environment:

128c128
< if ($this->ufClass == 'CRM_Utils_System_Joomla' || $this->ufClass == 'CRM_Utils_System_WordPress'){
—
> if ($this->ufClass == 'CRM_Utils_System_Joomla'){

2. edit <your_wp_location>/wp-content/plugins/civicrm/civicrm/CRM/Utils/System/WordPress.php
to load the bootstrap using an instance of CRM_Utils_System_WordPress class rather than calling it as a static method ( calling it as a static method results in errors when called from SOAP layer due to some changes that happened in CRM_Utils_System_WordPress::loadBootStrap and CRM_Utils_System_WordPress::cmsRootPath functions, in particular the fact that they now contain calls using a $this instance rather than static calls to self:: as before and when called from the SOAP layer $this means SoapServer instance which results in errors):

< self::loadBootstrap($name, $password);
—
> $config->userSystem->loadBootstrap($name, $password);
