Push Timecop to development dependencies

[madejejej]

In the gemspec the Timecop gem is listed as a regular dependency:

  spec.add_dependency 'timecop', '>= 0.1.0'

You probably want to include it only as a development dependency since it's only being used in spec/knapsack/tracker_spec.rb:

https://github.com/ArturT/knapsack/search?utf8=%E2%9C%93&q=Timecop&type=

It is used here:
https://github.com/ArturT/knapsack/blob/master/lib/knapsack/tracker.rb#L84

def now_without_mock_time
  Time.now_without_mock_time
end

now_without_mock_time is Timecop method: https://github.com/travisjeffery/timecop/search?utf8=%E2%9C%93&q=now_without_mock_time&type=

Anyway thanks for checking :)

Note to myself. It was done this way on purpose. Timecop is a regular dependency and I don't want to use Time.now because someone could stub Time.now and that would prevent to determine the correct time.

I figured out how Timecop gem could be moved to development dependencies. I did change in knapsack_pro KnapsackPro/knapsack_pro-ruby#38

A similar thing could be done here in knapsack gem. If anyone wants to help it's basically copy & paste from the PR

This could be an easy task for someone new who would like to contribute to open source.
