Add a .list() method to Dotenv

[pwoolcoc]

Currently, I am writing a gradle plugin for .env files, and it would be nice to be able to iterate over the list of variables that were defined in the .env file

[cdimascio]

@pwoolcoc thanks!
this is good idea. will have a look

[pwoolcoc]

@cdimascio I see you added and then commented out an iterator for it -- are you planning on un-commenting that at some point? that would work for me just as well as a list would, tbh

[cdimascio]

@pwoolcoc yes. I commented it out as it needed some work. The types weren't working out well on the Java side. I believe I have it resolved now

All in all, I borrowed many of your ideas
The PR is here, feel free to comment. I'm happy to make adjustments. I believe it now meets your needs.

The change is available in v4.1.0. It should make it to MavenCentral within ~24hours

@pwoolcoc FYI: If you want to try it out before it makes it to MavenCentral you can get it from JCenter with the following:

If you need it more quickly you can resolve to JCenter with the following:
Gradle

repositories {
    maven {
        url  "https://dl.bintray.com/cdimascio/maven" 
    }
}
