The usage of "Wii Remote" and "Wiimote" in the interface is inconsistent. "Wiimote" is also not a real word nor is it an official product name. Therefore I have changed instances of "Wiimote" in the UI to instead say "Wii Remote". I also made a couple of minor grammatical changes as well.
This is mostly a resubmission of #4338 but there are some minor other changes as well.
With the release of 10.12 Sierra OS X is now officially known as macOS. I changed all instances of "OS X" to "macOS" in the readme.
I also made a couple of other minor adjustments. The slash in the title was removed as other slashes were previously removed from the readme and it no longer made much sense with only two items to list. Also the Android section formatting was modified to better match the PC section.
To match Microsoft's recommendations better, Dolphin now has 16x16,
32x32 and 48x48 bitmaps in both 8-bit and 32-bit, in addition to the
256x256 32-bit bitmap. There used to be an 8-bit 32x32 bitmap but no
32-bit 32x32 bitmap, which led to Windows using the ugly 8-bit bitmap
at some sizes.
