Allow defining several custom FPS limits for toggling

[Calinou]

Right now, to define a toggleable FPS limit, you must specify more than one FPS value (0 is valid and acts as "unlimited"):

However, in the Custom field, you can only enter a single number:

This could be done by replacing the spinbox control with a standard text field, so you could enter something like 120 / 60 / 30 like in the presets. I'd like to use 0 / 117 so that I can toggle a 117 FPS limit when needed (this is to achieve low input lag with VRR on a 120 Hz display).

Hi @Calinou , i'll work on that for next release. Thanks for the feedback
