These 2 small updates address 2 issues:

• stairs rendering has been greatly improved, specifically to support for "long" stairs (see below)
• on the Windows client, when saving a file or exporting an image, it was possible to "forget" adding the extension (such as .png or .json), leaving you with improperly named files (ie. "MyDungeon", without extension). Now, when saving a file, the app ensures the extension is correct (ie. "MyDungeon.json").
