players: timestamp returns a round number now

Had some issues with it.
police: new functions, fixes, command, debug

Switched setPlayerArrested to arrestPlayer, and also added unjailPlayer.
Moved resource settings into s_police_jails.lua and added a new debug
setting.
Added new exported functions, such as the unjailPlayer, getJails,
getJailSettings, setJailSettings.
Added new /unjail command for the police.
Minor fixes, changes and such, just enjoy.
