Subject: Updated the Fluid IDE support for the current source file structure.
 Changed the Fl_Tree rendering code around a bit to make the tree more like
 MSWindows on Windows and more like Apple on Apple machines. I hope you guys
 like it. I also moved the function to load Fl_Preferences into an Fl_Tree
 into the Fl_Tree class where it belongs.
