* Add classes for application and project * Removed all globals from Fluid.h * Extracting args and project history into their own classes * Moving globals into Application class * Initialize values inside headers for some classes. * Undo functionality wrapped in a class inside Project. * File reader and writer are now linked to a project. * Avoid global project access * Nodes (former Types) will be managed by a new Tree class. * Removed static members (hidden globals) form Node/Fl_Type. * Adding Tree iterator. * Use nullptr instead of 0, NULL, or 0L * Renamed Fl_..._Type to ..._Node, FL_OVERRIDE -> override * Renaming ..._type to ...::prototype * Splitting Widget Panel into multiple files. * Moved callback code into widget panel file. * Cleaning up Fluid_Image -> Image_asset * Moving Fd_Snap_Action into new namespace fld::app::Snap_Action etc. * Moved mergeback into proj folder. * `enum ID` is now `enum class Type`.
