measure line bearing

[andersd]

The segment line bearing is using the e/w as the reference line for calculating bearing. It should use the n/s line. The bearing values should increase from DUE NORTH from (N0-0-0-E) when you move to DUE EAST (N90-0-0E). The bearing values should also increase from DUE NORTH (N0-0-0W)when you move to DUE WEST (N90-0-0W). Like wise values should increase from DUE SOUTH (S0-0-0W) to DUE EAST (N90-0-0E). This issues occurred in the 2.4 Oregon version and was fixed by Dan.

In the MeasureBearing.JS it appears that:

var degrees = Math.atan(rise/run) / (2*Math.PI) * 360;

Should be:

var degrees = Math.atan(run/rise) / (2*Math.PI) * 360;

This appears to make it work but my rusty math is usually worse then my js.
