Move a few settings from client.conf to features.conf

[EPuncker]

There are a few settings in client.conf file that would fit better the features.conf file since they are client (packetver) dependent, like:

• display_status_timers
• mvp_exp_reward_message
• ping_timer_inverval
• ping_time

(not sure about the ones bellow but I don't think they are present in all clients)

• packet_obfuscation
• display_rate_messages
• display_config_messages
• display_overweight_messages
