Linted data module
Fixed #3380, a regression causing Series.update not to honour updated zIndex.
Better solution for #3284 by making the entire numberFormat method settable and wrappable from the outside.
Fixed #3434, error 10 throwed with null values on logarithmic axis.
Fixed #3431, regression causing error 16 not to be triggered.
Fixed #3436 causing round linecaps on median lines in box plots. Reverted fix for #1638, a workaround for a Firefox bug regarding linecaps. Newer Firefox versions don't have the bug.
Fixed #3437, data module failing with numeric data in first column
