scales 1.1.1

• breaks_width() now handles difftime/hms objects (@bhogan-mitre, #244).

• hue_pal() now correctly inverts color palettes when direction = -1
  (@dpseidel, #252).

• Internal precision(), used when accuracy = NULL, now does a better
  job when duplicate values are present (@teunbrand, #251). It also does a
  better job when there's a mix of finite and non-finite values (#257).

• New oob_keep() to keep data outside range, allowing for zoom-limits when
  oob_keep is used as oob argument in scales. Existing out of bounds
  functions have been renamed with the oob_-prefix to indicate their role
  (@teunbrand, #255).

• ordinal_french() gains plural and gender arguments (@stephLH, #256).
