* 1.1-stable: (46 commits)
  one line is enough ... `lines -= 5`
  update for next dev SNAPSHOT
  prepare for 1.1.20
  setup testing against rails 5.0 beta1 (using rack 2.0.alpha)
  re-invent missing Rack::Utils.bytesize (2.0 will work) + prefix ::Rack constant!
  [travis-ci] let those jossl issues fail until there's time to figure out (can not reproduce)
  [travis-ci] 1.7.16 has loading issues with jossl thus try 1.7.4 instead
  use recent jruby-openssl that works better with all jrubies
  fill in release notes for 1.1.20
  pre-maturely avoid Ruby frozen string literals coming at us ... ''.dup meh!
  fix broken controller.servlet_response spec from jruby#201
  allow to boot when RAILS_ROOT/public directory does not exist (closes jruby#197)
  for better booter detection - export public path after working directory was changed
  improvise more rails boot isolation in "stub" spec - now that more of it runs
  adjust stubbing setup - do not unshift LOAD_PATH in spec_helper
  stub-ed specs have not been running - change that and re-invent rails stub .rb files
  Add a `ActionController::Base` method to return the `servlet_response`
  adjust jruby home dir fallback (for default $LOAD_PATH) correctly on 9K and --2.0
  (c) 2016!
  bundle update jruby-openssl
