Enhance the 'thetime' command by using GeoIP timezones with shifting if needed

[regener]

As mentioned in the title display the time based on user's IP to give them the real time they are looking for and not for the server time.
The idea is came by because many servers has other timezone that they should have, that is a hosting thing, I don't know the reason.
Also helps players from other country than the server to get real time.

An approach like this could be good:

Getting the user's IP, then getting the timezone he/she is in, at last shifting is made if needed.

@evandrocoan, Beyond the user time, also show the server time.
