slate next release in changelog, and tweak some formatting
make internal method private
consistent method signature
consistent digest instantiation
use custom error class vs. regexp on string. use less terse fail names
add explicit dep.
remove redundant parens
avoid changing method visibility from omniauth-oauth2
consistent max. line length to 120. use tomdoc comment style
update code to be consistent with max. line length of 120
version dep. strategy is an app concern, keep readme neutral
add note that 1.6.0 in changelog is unreleased. [ci skip]
line break so it looks nicer
prepare for 1.6.0.rc1
