Mac build issues

• Ghosts now have a self lighting (changes every 3 seconds between ghosts because JavaFX allows only 3 point lights at a time?)
• Try out updated Gradle scripts

• Improved swirl effect

• Improved heap space consumption
• New energizer explosion animation

• Fixed nasty memory leak

Fix: Directories were not created on first run

Fix: Ghosts could go through walls, Ups!

Huge simplification of map creation when template image is available:

• Drop map image into the editor and pick the 4 colors (fill, stroke, door, food color) using the context menu
• Enter Edit Mode (S or E) and select menu entry "Edit -> Identify Tiles"
• Set Pac-Man position and add tunnel tiles if any
• Done!

Map format has changed: No double-stroke wall and rounded corner tiles anymore, only angular ones which are used internally to detect the ghost house in a map created from an image.

Old custom maps can easily be updated to the new format by loading them into the map editor, setting the house position (context menu entry "Place House", open context menu over left-upper corner of house) and saving the map.
