cuberite-2a/source/cServer.cpp
faketruth 738b1b3467 Improved Core's WebAmin interface a bit. 
Can now kick players through WebAdmin
Can now enable/disable whitelist through WebAdmin
Tick speed is limited in a better way now, instead of always sleeping 50ms before each tick, it now add only sleeps additional time when the tick time was faster than 50ms. Server should run slightly faster because of this (and use more cpu%)
