Title: Fix exception when y_axis_increment is used in line bars

Setting y_axis_increment manually with a line graph will fail with this message:
gruff-0.3.6/lib/gruff/base.rb:687:in `normalize': wrong number of arguments (1 for 0) (ArgumentError)

The problem was a missing argument on normalize in the Line class. I added a test and fixed the code.
