dependency on activesupport 4.x is a blocker for rails 5.x

[net1957]

on a new project on rails 5.0.2, this gem install only in version 0.5.3

on activesupport 5.0.2 it seems that the required files exists.

Perhaps you could relax on activesupport version ?

First problem is due to rake 11.x so i added in the Rakefile

# temp fix for NoMethodError: undefined method `last_comment'
# remove when fixed in Rake 11.x
# see http://stackoverflow.com/questions/35893584/nomethoderror-undefined-method-last-comment-after-upgrading-to-rake-11
module TempFixForRakeLastComment
   def last_comment
     last_description
   end
 end
Rake::Application.send :include, TempFixForRakeLastComment
### end of tempfix

I did modify proxy_pac_rb.gemspec:

  spec.add_runtime_dependency 'activesupport', '>=4.1', '<5.1'

and i tried with activesupport 5.0.2
it's working,
but for testing i get

 middleman (~> 4.1) was resolved to 4.1.0, which depends on
    middleman-core (= 4.1.0) was resolved to 4.1.0, which depends on
      activesupport (~> 4.2)``

I relaxed version of uglifier and middleman; I get activesupport 5.02, middleman 4.2.1 and uglifier 3.2.
but some test fails:

  1) ProxyPacRb::Rack::ProxyPacCompressor when valid proxy pac is given should eq "function FindProxyForURL(url, host) {\n    return \"DIRECT\";\n}"
     Failure/Error: it { expect(body).to eq compressed_content }

I have a temporary fork on https://github.com/net1957/proxy_pac_rb with a rails5.0 branch

[net1957]

replaced the rails5.0 branch with a rails5.1 one
