Add TV show options to the general window, with the following options.

TV show update on startup, this works together with the --force option at startup. Making it optional in the config makes it easier for novice users.

TV show update time, the current update time is hardcoded to 3 o clock. Making it optional gives users that don't have sickbeard running 24 hour the ability to update the TV show content automatically.

I added this change earlier, but something went wrong with the project. If there are some other options that are hardcoded please let me know, I can also added them to the option file.

This option is related to the following topics, and I picked it up because I also run into a lot of out of date show information because my laptop is not on at night.

To make sure we do not spam thetvdb.com with to many requests I would suggest to put in something that checks when the last update is done. (so it will start a new one 24 hours after the last one)

new code should be submitted against the development branch, can you please rebase?
