Allow configuration of teardrop angle.

[martinbudden]

In most cases a teardrop angle of 45 degrees is fine, but there are cases when this does not give sufficient overlap between layers and a slightly steeper teardrop angle, say 50 or 55 degrees is desirable. This change allows this.

The teardrop angle is defaulted to its current value of 45 degrees.

In particular I print mostly functional parts and for these (for both strength and speed of printing) I tend to use a 0.6mm nozzle with 0.5mm layer height and 1.0mm extrusion width. For these large layers, a teardrop angle of 50 or 55 degrees gives better results.

I normally merge using the command lines provided by the PR. It worked yesterday but I don't see any today on the remaining PRs. Even the PSU one I am part way through merging.

I'm not sure what you mean - is there some kind of problem with github?

Yes either GitHub has changed overnight or I have gone blind

With a diagram I worked out x is simply tan(teardrop_angle /2) and Wolfram says that is equivalent:

So the top of the teardrop is 2 R tan(a/2), where have I seen that before today, LOL!

I will simplify it when I merge. It's a pain now Github doesn't give the commands anymore. I have to type them all manually.
