improve beds detection and rewspam fixed if re-joins with no dead

* when player re joins, respawn agains so remove code for rejoin
* player must be in same position form last time if are alive
* improve commit 2b50e329f0 and 004e8dabe7 due we need beds checks
* depends.txtx abd make beds optional so we can chek the beds global var
* return true when finished the respawn find ground.. i dont know but works
* that return is need in the respawn callback function of the player
