Fixed bugs in ColorPicker.setColor, where the specified color was not
always set correctly.
Implemented different sizes in ColorPicker, SVBar and OpacityBar, so it
fits better on small devices.
Fixed pointer position on bars, that was wrong because of the size fix.
Fixed wrong pointer position for bars in configuration change.
Removed the round method, because Math.round does exactly the same.
Merge pull request #14 from frigus02/master
