Reserve Teamwork elements and sets

Reserve elements, and non-element object sets, in a Teamwork project so you can edit them (Tapir). CONFIRM-GATED: without confirm=true it only reports what it can learn without touching the server: not_found, already_mine, and would_attempt. Whether another user holds an element is only learned by attempting, because Archicad exposes no read for it. With confirm=true returns reserved, reserved_by_others (with the user's name), already_mine, not_found, and indirectly_reserved: elements Archicad pulled into your workspace that you did not ask for, such as a door's wall. object_sets reserves what attribute, property and classification edits need: an attribute type (Layers, Composites, Fills, Lines, PenTables, Profiles, BuildingMaterials, Surfaces, ZoneCategories), Properties or Classifications, or any Archicad set name (Favorites, ProjectInfo, ...); needs Tapir 1.7.1. Each set's entry says status, held_by and outcome (would_reserve, already_mine, held_by_others, reserved, failed); for sets the dry run does know who holds them. A reservation is visible to every teammate and blocks their edits until released.
