Incomplete arc

[zsoltk]

I'm trying to implement my own ColorAdapter, and I found that sometimes the arc is incomplete. I'm guessing this is because in the implementation of LobsterPicker.getAngle(int position) segmentWidth is calculated using integer division:

int segmentWidth = 360 / nbOfSegments;

So when my adapter has 16 colors, 360 / 16 = 22.5 is treated as 22.

When I reduce the number of colors to 15 (360 / 15 = 24), the arc is complete.

See a screenshot here.

Thanks for the great library!

@zsoltk Yes I think that's the issue, Currently I'm totally out of time to fix this issue. A pull request is much appreciated.
