Fix modifier key handling in OS X to allow command-keys to work.
A variety of modifier key handling issues are addressed in this CL:
- Added a skui::Key for the Super key (this is ImGui's name for command)
- Added OS X event handling for `flagsChanged` (sent when modifier keys
are pressed)
- OS X manually tracks modifier key state and sends key-up and key-down
events to the ImGuiLayer as necessary
- OS X does not send key-up events when hotkeys are pressed, so these
are manually synthesized and sent to ImGui (otherwise hotkeys are
repeated forever)
- Replaced hardcoded Virtual Key valus in OS X code with named constants
- Our custom bitmask type was lacking the ability to XOR
This CL does NOT enable the OS X clipboard; this uses the ImGui internal
clipboard.
