hrui: Hide normal "Employer/Job title" fields

When the extension "org.civicrm.hrui" is installed, the normal "Employer" and "Job Title" fields should not appear on the "View Contact" screen.

Aside: Not sure if you have a better idea, but this might be accomplished by adding some CSS? e.g.

function hrui_civicrm_pageRun()

{ ... CRM_Core_Resources::singleton()->addStyleFile('org.civicrm.hrui', 'hrui.css'); ... }
