Info panels stay in their box, menus show real labels

Two fidelity fixes for content-heavy pages. When a page wraps a list inside a table cell - the way an encyclopedia builds its side info panels - the cell now wraps to fit its column instead of stretching wide and painting over the text beside it. And menus that were showing raw placeholder text now show their real labels: the engine now reads a page's inherited object properties when a script loops over them with for...in, a standard behaviour many sites rely on to build their menu and settings labels.
