-changed some logging to get better informations for debugging

-Moved the default position of the effect frame downwards.
-The skill dialog can now only be opened when the server sent the player skill set to the player.
  -This is to prevent a client side crash that can occur when the player tries to open the dialog before the server sent the data.
  -This should only be a really small time frame. (something like 0.5 seconds after joining a server at maximum)
