Layout editor

NOTE: MyGUI does not support plugins for Mac OSX yet (https://github.com/MyGUI/mygui/issues/42), so editing OpenMW layouts is currently not possible on that platform.

Currently a git master version of MyGUI is required, but the needed features will be included in the next release 3.2.2. When 3.2.2 is released, compiling will no longer be necessary and a package can be used.


 * Download, compile and install the latest git master version of MyGUI from https://github.com/MyGUI/mygui.
 * Rebuild OpenMW against the new MyGUI version you just installed. An OpenMW version from git master (39b6659045ae07c7c4539efbb46241dd288fc59e or later) is currently required, which includes a MyGUI Plugin library called Plugin_MyGUI_OpenMW_Resources.
 * Copy the Plugin_MyGUI_OpenMW_Resources library file from the OpenMW build folder to the directory you will be running the MyGUI Layout Editor from (most likely the "bin" subdirectory in MyGUI's build directory).
 * Start the MyGUI LayoutEditor.
 * Go to File -> Settings -> Folders, press Add and select the folder in your OpenMW repository containing the MyGUI layouts (files/mygui)
 * Go to File -> Settings -> Resources, press Add, type core_layouteditor.xml, then press Enter.
 * Restart the LayoutEditor and try to load a .layout file from OpenMW. It should be working now!
 * Note that when you save a layout, you need to run OpenMW's cmake script in order to copy it to OpenMW's build folder, so that the new layout is used when you start OpenMW.
