Map outline completion

The map outline has now been completed so I can finally start concentrating on the actual layout and finer details of the map itself.

I've also finished the import from Pyxel Edit into the game and the video shows a quick device recording so apologies for the jerky movements. You’ll also have to excuse the black right border, it’ll be covered by UI so it didn’t need to go to the edge of the screen

One minor issue which is going to annoy me is there's a small line between each tile. This is a pixel or so from the Java bitmap selection functionality I'm using to get part of the tileset onto a Sprite. Not a huge issue, it's just going to bug me til it's sorted.
