Teleport should move players to the center of the block (x +.5, z +.5)

CMDBOOK-2157 - Reported by DailyCakeSlice

When I use the teleport command, (I happen to use /tp psplayer 100 69 100) it literally puts me there. Without the plugin, if I issue that command, it puts me at 100.5 69 100.5. It also does the same to command blocks. I happen to need the default server teleports, the one where tping to 100 69 100 really puts you at 100.5 69 100.5, because I make maps, and the commandblocks need to teleport me to a specific block, not in between them like world edit does. If you could please add an option for worledit to override regular TPs or to leave it alone, I'm sure this would help many people. Thanks, Gavin.

未指定文件或测试。首先跟踪 teleport 命令和命令方块传送处理，然后确定方块坐标如何转换为玩家位置。Done 应与请求的居中坐标匹配，同时保留或明确配置服务器的默认传送行为。
