Proposed changes

The floor id could only be set with the command line option when starting the UI and was not stored in the floor JSON, although floors depend on the seed and the floor id since the generator improvements. The JSON now contains the floor id, older files without it still load, and the seed stability test only hashes the floor content so new metadata does not change the pinned floors. The UI has a floor field next to the next seed, Page Up and Page Down change it, and the status bar shows the seed, floor id and history position of the shown floor. This also fixes the history, which contained every discarded attempt of a generation instead of only the final floor.
