EasyRPG rev 1542 - Main Window and Maptree HD

This is the new EasyRPG editor, written in Vala and GTK+. It replaces the old C++/WxWidgets editor. The main window is very similar to the RPG Maker one, with the same toolbars and menu items. The icons are not definitive. The project file (.rproject) stores info about the map, layer and scale used in the last session. The maptree loads correctly, keeping the tree-structure of the maps. It supports drag&drop and scrolling. The maps can be reordered freely. (EasyRPG rev 1542) Web: http://easy-rpg.org
