Clarify in README that dotenv gem is still required

[pelargir]

I was confused for a bit because my .env file wasn't being loaded. I assumed the dotenv gem was a dependency of the dotenv-deployment gem but I guess it wasn't. You should clarify in the README that both dotenv-deployment AND dotenv have to be added to the Gemfile before things work as expected.

+1 had the exact same problem.

Had the same problem also. This has to be clarified in the readme.

Shouldn't there be a runtime dependency in the gemspec, so this will work automatically?

The next release will have the dependencies declared properly. I had to do it this way so it didn't break for people upgrading from previous version.
