Improved formatting functions

date_format() gans an option to specify time zone (#51).
dollar_format() is now more flexible and can add either prefixes or suffixes
for different currencies (#53). It gains a negative_parens argument
to show negative values as ($100) and now passes missing values through
unchanged (#40, @dougmitarotonda).
New ordinal_format() generates ordinal numbers (1st, 2nd etc)
(@aaronwolen, #55)
New unit_format() makes it easier to add units to labels, optionally
scaling (@ThierryO, 46)
New wrap_format() function to wrap character vectors to a desired width.
(@jimhester, #37).

New color scaling functions col_numeric(), col_bin(), col_quantile(),
and col_factor(). These functions provide concise ways to map continuous or
categorical values to color spectra.
New colour_ramp() function for performing color interpolation in the CIELAB
color space (like grDevices::colorRamp(space = 'Lab'), but much faster).

boxcox_trans() returns correct value when p is close to zero (#31).
dollar() and percent() both correctly return a zero length string
for zero length input (@BrianDiggs, #35)
brewer_pal() gains a direction argument to easily invert the order
of colours (@jiho, #36).
show_col() has additional options to showcase colors better (@jiho, #52)
Relaxed tolerance in zero_range() to .Machine$double.eps * 1000 (#33).
