soap.php throws an error when authenticating in Joomla

authenticating against soap.php results in an error in Joomla:

Call to undefined function jimport()

This error is thrown from CRM_Utils_System_Joomla::authenticate line 439 and happens when $loadCMSBootstrap == false. jimport is an internal joomla function and is only available when the joomla environment is loaded.

I was able to repro on Joomla 1.7.5 and Joomla 2.5.1 with CCRM 4.1.0 and 4.1.1

I attached a patch for making this work for soap, however in the current form CRM_Utils_System_Joomla::authenticate will always fail if $loadCMSBootstrap == false.

So perhaps there also needs to be an exception thrown when $loadCMSBootstrap is passed as false saying that this param being false is not supported on the joomla platform.
