Corrected notification function
Use von for gmod

It was overriding von modules by other addons(wiremod) and causing
issues.

Fix #101
Fixed not usable console-commands like "ev map"

The function checked only if plugin.ChatCommand was a string - changed it now to same behavior than sv_chatcommands to also check if the plugin.ChatCommand is using a table.

So this fixes for example the use of map change plugin from console.
