MapMe: DnD 5e Battle Map Maker

Bugfixes: * Flipping then Duplicating don't mess up Objects anymore * Fixed a rare crash where importing images would crash the app * Fixed a rare bug where Maps Froze after opening the app again Shape Layer Revamp: * Drawing Shapes is now possible with the finger or pencil (it uses "auto adjusting curves" meaning no more bezier handles for those paths!). * Also there is a Merge Option on Shape Layers, which causes all shapes to be merged where they meet, making it SO MUCH EASIER to create complex structures. * You'll also noticed I have combined the Path and Pattern Layers into one. There's only "Shape Layers" now which makes things much easier to handle in code. All existing maps will be migrated. * You can also turn on "Corridor" mode on paths, letting you easily create corridors & pathways which, together with merge mode, make is super easy to create dungeons and caves etc. * Corridors can now also be "naturalized" essentially wiggling the shape and width of the corridors to make natural looking pathways if you're going more for a cave style corridor * Shapes can now also Properly be closed.
