Provide sample Velocity configuration

[synrg]

Tested:

• detects Done when mark2 start performed
• issues end when ~stop performed
• sends alert when ~stop 1m performed (i.e. 1 minute warning received by player on server behind the proxy)
• lists player in player pane when they join
• removes player from player pane when they quit
• quit message detected whether they quit normally or abnormally (i.e. (?P<reason>) is non-empty only for the latter)
