Indicator for price trend

[y]

Adding an indicator if the price is trending up or down would be nice. Maybe an arrow, or change the color of the bitcoin symbol green or red depending on direction.

@y: Thanks for the feedback! This requires time series data to be useful, so I've had this sketched out for awhile for a major revision of btcbar that also shows graphs of recent trends. I think it's going to have to log data locally though since not many of the APIs offer historical data for free.
