Remove xref methods now in LibertyContent; update callers

Nine methods deleted from Contact (getContactGroupList, getContactSourceList,
getXrefTypeList, getXrefFormatList, loadContentTypeList, loadXrefList,
loadXref, storeXref, stepXref) — all now inherited from LibertyContent.

Contact sets $mXrefTypeKey = 'contact_types' so loadXrefTypeList() continues
to store under the key templates expect. load() updated to call
loadXrefTypeList(). Page files updated: getContactGroupList → getXrefGroupList,
getContactSourceList → getXrefSourceList.
