Traps and doors made in a new forge room, installed by imps; new creature: the cogling

- forge room: creatures work there (coglings fastest), the work goes into the oldest planned trap or door; finished pieces wait as crates, imps carry and install them
- traps: spike pit, poison vent (cloud), fire jet, stone roller, alarm bell (calls creatures), rune mine (one big blast), frost glow (slows around it)
- doors: wood, iron, magic (hurls attackers back); own creatures pass, enemies smash them on their way; clicking a door with a door tool locks it for everybody
- new 'Traps' category in the toolbar, forge in the rooms; texts EN/DE, bestiary entries; atlas grown for new textures and icons
- tests: forge to installed trap, spikes hurt, doors lock and get smashed
