update changelog

add lib to test task libs, set warning to true
Surpress warnings in Base#interpolate when too many interpolation arguments are passed

This is a temporary workaround. We should reimplement #interpolate in C to both get rid of the warnings and speed up various things.

We definitely do not want any warnings here because translators need to be in control of picking up or omitting interpolation arguments in their translations. Example: { :zero => 'No messages', :one => 'One message', :many => '%{count} messages' }
get rid of warnings in 1.9.x
include files in ci and test directories to gemspec
add minimal development dependencies to gemspec

we're using Gemfiles in ci/ in order to setup different contexts. this might change in the future. this commit includes development dependencies that are required to run core tests (the test setup will skip certain tests that require, e.g. rufus/tokyo)
