Add outputDirectory and outputName;

[Vivalldi]

Resolves #61

Introduces

• JEST_JUNIT_OUTPUT_DIR:outputDirectory - Directory where xml file will be stored
• JEST_JUNIT_OUTPUT_NAME:outputName - File name of the test results. (Default junit.xml)

This change is introduced in a backwards compatible manner. Personally I think that we should recommend users to move to the new configuration options and depreciate the output/JEST_JUNIT_OUTPUT options.

I believe my builds are failing due to an update in jest. By passing the --env node flag to the jest command the tests will pass locally.

This repo should probably specify testEnvironment: node in its config. No reason to run in jsdom.

@Vivalldi please rebase and see if the tests pass. I updated the suites to use the node environment here #64

That did the trick 👍
