Make actionview an optional dependency

[manuca]

Resolves #5

@manuca I understand that actionview can be an optional dependency because of this:

https://github.com/fastruby/next_rails/blob/master/lib/next_rails/gem_info.rb#L1-L5

And this: https://github.com/fastruby/next_rails/blob/master/lib/next_rails/gem_info.rb#L55-L59

But I have a question about activesupport.

@manuca How come this is necessary now?

@manuca How come this is necessary now?

@etagwerker This is the culprit:
https://github.com/manuca/next_rails/blob/make-actionview-optional/exe/bundle_report#L59

@manuca Weird. And where is that code getting called? What methods are we using from active_support?

[manuca]

Which to be honest I have no idea why we're depending on it as there are no acts_like? calls anywhere as far as I've searched.

For reference this is acts_like.rb:
https://github.com/rails/rails/blob/5-2-stable/activesupport/lib/active_support/core_ext/object/acts_like.rb

@etagwerker I removed the activesupport dependency. Specs pass and bundle_report seems to work as expected.

@manuca Interesting. I ran into the reference to acts_like? in v1.0.3: #21. I guess it is getting used in the exe command.

@manuca Great, thanks! 👍
