Add bounding-box object alignment (ALIGNLEFT/TOP/etc.), ported from Mac2CAM

Six one-shot alignment commands for the current selection — ALIGNLEFT/ALIGNHCENTER/ALIGNRIGHT/ALIGNTOP/ALIGNVCENTER/ALIGNBOTTOM — distinct from the existing point-picking ALIGN/ALIGN3D command: each nudges every selected object (or complete group, via new Scene::selected_object_units) so its bounding-box edge/center lines up with the extreme edge/center already present in the selection, closer to a word processor's "align objects" than AutoCAD's 3-point ALIGN. Wired as plain one-click Tool entries in the Modify extension panel, next to the existing ALIGN entry, matching that panel's flat-list convention (no point prompts, so no dropdown submenu needed).
