add a warning system

[alexpvpmindustry]

warns the user until the warning threshold.
if warn number reaches the warning threshold, kicks the player to alex hub xD.
feel free to change the URL, or to change it to just plain kick.

ActivityInfo not saved in settings.bin. It for game session and warnings may be reset when player disconnected

this is ok i think. not necessary to save more stuff into settings.bin.
if the player re-logins, we could consider the player as non-afk (since the player will probably need to click on a few buttons).
if the player uses an auto-login macro or bot to reset the afk warning, then he could have easily just moved his ship to avoid the afk kick in the first place.

The warning does not warn in some servers .-. . Pretty sure in some of the pvp servers
