Make the default trending smarter

[#1]

When you switch from rank to trend, the report always defaults to "day" and you have to then change it.

If my timeframe was 30 days, that's fine. But if my timeframe was 12 months, do months, if it was 52 weeks, do weeks. If it was 59 days, then I suppose days would still be the default; in short, save me the obvious step by setting the level to the nearest large-block-division of the selected timeframe.

Yes! Can't tell you how much time I've spent waiting for page load when switching from ranked to trended view when the time period is a year and SiteCatalyst decides I want a daily trend.
