Bug fixes and functionality

Fixed a bug with setting count_past_zero giving errors.

Added functionality that lets you set what time circles views as the "total duration".

By default, the total duration is 1 year (or more accurately, 365 days), however you can now also set it to a month (meaning the "Days" timer would be roughly half full at 15 days).

By setting it to "Auto", TimeCircles will simply look at which values you're showing- and pick something bigger than your biggest unit.

Other available settings are: "Years", "Months", "Days", "Hours", "Minutes".

You can also give this variable a numeric value (in seconds). So, if for example you're only showing the 'Seconds' timer, you can set total_duration to 100 (Or any other value).

Simply do:
$("Countdown").TimeCircles({ total_duration: "Months" });

To use this setting.
