BCEA 2.4.7 CRAN

• In ceplane.plot() for {ggplot2} version used the ggplot syntax thats already used for other plotting arguments so that we can now pass, e.g. wtp = list(value = 20000, colour = "blue", x = 10, y = 10, size = 4). This closes issue #151 so can do something like wtp = list(size = 0) to hide the willingness to pay text. (3d8a770)
• Small features added which were missing for the new edition of the BCEA book:
  • Extended ggplot version legend to take a vertical or horizontal part to the pos argument (85ba87f)
  • Relative font size argument rel for ceplane and ceac plot (8d1586f)
  • Added text size ggplot argument to eib_plot (1e32788) and evi_plot (84aaa2f)
  • label.pos logical argument fixed in ceplane.plot for ggplot (92e9eb0) and base R (c7351e4)
