This is an Android port of 7ed61c50a1. It looks like we don't have
descriptions for any of the RetroAchievements settings in the Android
GUI, so I haven't added descriptions for these two new settings either.

Modify the RetroAchievements login code in Android to pass in a callback, pop a message if login fails, close the login box if it succeeds.

Android: Add Reset Dolphin Settings functionality

IOS/USB: Emulate Wii Speak using cubeb

This feature allows overriding the frequency of the Vertical Blank Interrupt. For many games, this means that their gameplay speed will change without affecting audio, which would be useful by itself (e.g. grinding in RPGs).

However, there are games that use delta time for their game logic, which allows them to be played at >60 FPS at the same gameplay speed!

Some games aren't dynamic though, and require a patch to adjust their game speed variable.
