Since version 1.9.1 the watch task crashes by an error, when changing a file... strange :-/

* Refactored the class again to use weights instead of sizes for rating entries
* Simplified sub routines to be more efficient
* Initializing helper object and doing checks in client event listeners

TODO: Move settings for flooding protection to config

* Always show number of players
* Hide players list, if it is empty, allow overwrite by using css class "secret"
* Have four "formSection" containers in server tab
* Added css class for tab pages
* Tab title/channel name is now contained in span tag
* Tab headers having tooltips showing the channel name

Note:
Because translations are set to DOM in escaped form, the texts have to be decoded before.

On disconnect, sockets are in no rooms anymore - even before kicking them out manually.
Because of that, removeClient() did cancel in beginning...
But anaway, we have to remove the client from the unique users list - so force it.

This will temporary leave the channel...

TODO:
- Button for temporary leaving custom channels (Leave with param true)
- Flooding protection!
-- Add closure to client socket, which handles counting emits (By SocketHandler)
-- All client event handlers must call counting method of closure
-- Disconnect client on threshold overflow...

Not finished yet...
