Increasing skillchain limit

[Jakuk]

The reason is not due to the cap on the number of ws allowed to participate in a multistep sc though, it's the decreasing window for continuing them. Anything over 3step gets rather tricky to continue due to the timing (and broken by even a small lag spike) and gamers tend to prefer reliable/guaranteed results so risk/reward is deemed low enough for most to dismiss trying. Raising the window's lower limit would allow for us to go past the current 6step limit, so it could open up strategy possibilities if it was raised to 2sec at least.

I'm all for raising the window, but I still don't see many if any people going past 6step bar the first couple of days.
