Add supplier xref page; fix STOCKASSEMBLY_CONTENT_TYPE_GUID in StockBase

add_supplier.php + add_supplier.tpl: form to add a #SUP xref record
with supplier contact (filtered by $04 type), part number, price and
note in one step. view_xref_sup_group.tpl: smartlink updated to
"Add supplier" pointing to the new page. StockBase: define
STOCKASSEMBLY_CONTENT_TYPE_GUID with guard so it is available when
StockAssembly is not loaded (e.g. component view path).
