Define respond_to_missing? in base texter

[papa-whisky]

Attempting to expect a method call to a texter in RSpec results in a failure:

Failure/Error:
       expect(ExampleTexter).to receive(:send_text)
       ExampleTexter does not implement: send_text

This PR defines the respond_to_missing? method to remedy this, as recommended by community style guide.

@Lackoftactics or @sakirtemel any chance of a review on this?

This would be great to get merged - RSpec's verify doubles use respond_to? to validate the mocked object actually responds correctly.

# spec_helper.rb
mocks.verify_partial_doubles = true

# will error
allow(ExampleTexter).to receive(:send_text).and_return(message)

@NGMarmaduke Unfortunately it appears this gem is no longer maintained, there's been no activity from the maintainers since early this year. It's a pity because I think it's quite a nice pattern! Anyway, you might be better off just making your own fork for the time being.

@papa-whisky @NGMarmaduke You're right, the project was a bit abandoned for few months (and that's our fault) BUT thanks to your comments we're definitely willing to get back on track as we believe the project is really interesting and we should continue maintaining it. Next Tuesday we will have an internal meeting and hopefully, we'll pick it up from there pretty fast. Have a good day everybody!

Re-created the PR at #49 as retriggering build on TravisCI still remembers the old configuration.
