Fix Ramp Glitches

[ev0]

There are very little ramp glitches AFAIK on all maps. The tick rate is set at 102.4 due to this being the optimum tick rate for surf. Any higher and those glitches would be worse, lower and we reduce the hit reg severly and would make trying to hit moving targets very hard. AFAIK GRiver is the only map that can be played consistently on 128tick without many glitches(teles at bottom get the ladder glitch on the white circles)
