[Core] Read rerun files from directories

[dbfwhitney]

Added a method to try and add functionality to process all rerun folders in a directory (if more than 0 files exist). Still needs work as not sure how to implement walkFileTree method.

Looks good! Now there are a few more things that need to be done before this can be merged.

1. Write some tests.
2. Clean up the code
3. Update the CHANGELOG.md

Once that is done the feature can be released.

Writing tests

The test for this class would go into the CucumberPropertiesParserTest. There already is a test for should_parse_rerun_file so you can use that to pattern a few more tests. I reckon the important cases are a directory with no files and a directory with two files.

These tests will make the next part easier.

Cleaning up the code

I've left some comments on the code itself. They'll make the code a bit better.

Update the CHANGELOG

In the CHANGELOG.md file you can add a ### Fixed header and add an entry for your change. Have a look at the older entries to see the format used.

Pushed some changes. Still have to update the docs on @CucumberOptions, USAGE.txt, Constants.java, ect.
