Changelog:

  - Emulator::Interface::videoResolution() -\> VideoResolution renamed
    to videoInformation() -\> VideoInformation
  - added double VideoInformation::refreshRate
  - higan: added `binary := (application|library)` — set this to
    `library` to produce a dynamic link library
  - higan: removed `-march=native` for macOS application builds; and for
    all library builds
  - higan: removed `console` build flag; uncomment  `link += -mwindows`
    instead
  - nall/GNUmakefile: `macosx` platform renamed `macos`
      - still need to do this for nall/intrinsics.hpp
  - Game Gear: return region=NTSC as the only option, so that the system
    frequency is always set correctly
  - hiro/cocoa: fixed typo [Sintendo]
  - hiro/Windows: removed GetDpiForMonitor, as it's Windows 8+ only; DPI
    is no longer per-monitor aware
  - icarus: core Icarus class now has virtual functions for
    directory::create, <file::exists>, <file::copy>, <file::write>
  - icarus: Sufami Turbo can import save RAM files now
  - icarus: setting `ICARUS_LIBRARY` define will compile icarus without
    main(), GUI components
  - ruby/video/Direct3D: choose the current monitor instead of top-left
    monitor for fullscreen exclusive [Cydrak]
  - ruby/video/Direct3D: do not set `WS_EX_TOPMOST` on fullscreen
    exclusive window [Cydrak]
      - this isn't necessary for exclusive mode, and it just makes
        getting out of the application more difficult
