FPS automatically changing to Native

[themalu866]

On 0.7.2 I noticed that f I try to change the FPS Target on the Settings window it doesn't work and it always goes back to 59.7275.
I can only change it on the mgba window but if I go to the Settings window it goes to 59.7275 again, and I don't even need to change the FPS, it goes to Native automatically.

This is fixed in master. Please check a development build. I'll merge it for an 0.7.3 if there is one though.
