Changed settings.go to allow disabling the ratelimits.

Before, the settings parser would automatically reset the ratelimit
times to the default if you set them to zero. You could get around
this by setting the ratelimits to -1, but then the parser would
immediately set them to zero and write to disk. On next launch,
the parser would read the zeros and then reset the values to
default, so you would have to modify your ratelimits every
launch.
