Update example code snippet provided in the Wiki, and corresponding example plugins

[DeviousNull]

(I am unable to submit a PR for the Wiki, hence this issue)

This page:

• https://github.com/Yaribz/SPADS/wiki/SPADS-plugin-development-(Python)#user-content-Writing_plugin_code-2

... contains the following:

However, if SPADS is disconnected from the lobby due to network problems for example, all lobby handlers are automatically removed. So we must re-add them each time we connect to lobby server. This can be done using the [http://planetspads.free.fr/spads/doc/spadsPluginApiDoc.html#onLobbyConnected-self-lobbyInterface onLobbyConnected] event-based callback as follows:

   # This callback is called each time we (re)connect to the lobby server
   def onLobbyConnected(self,lobbyInterface):
       
       # When we are disconnected from the lobby server, all lobby command
       # handlers are automatically removed, so we (re)set up our command
       # handler here.
       spads.addLobbyCommandHandler({'SAIDBATTLE': hLobbySaidBattle})

However, based on advice provided by Yaribz, some commands may be missed if handlers are registered in onLobbyConnected(...) instead of onLobbyLogin(...). So, I believe this page should be updated to switch which callback is used.

Similarly, the example plugins which use onLobbyConnected(...) should probably be updated as well:
