Method getOptions

/*
 * Load Phoca Cart Options only once per site
 * Options can be different when they are called in administration or in site, or on com_phocacart site or not com_phocacart site
 * Component = PC (Phoca Cart)
 * Client = A (Administrator) | S (Site)
 * Option = com_phocacart
 *
 * Possible values:
 * PCAcom_phocacart - Phoca Cart component, Administrator, option=com_phocacart
 * PCScom_phocacart - Phoca Cart component, Site, option=com_phocacart
 * PCScom_content - Phoca Cart component, Site, option=com_content (we need options for Phoca Cart module displayed on com_content page)
 * (there can be some exceptions like if we call router where the option is not known yet)
 *
 * PhocaCartUtils::getComponentParameters -> PhocaCartUtilsOptions::getOptions (singleton)
