Adjustments to make this package useful for me

[williamatpaper]

In this PR I have added variables to support the following:

1. Allow the ability to change the "include_all" flag that the API uses to include all test cases when a new test run is created.
2. Allow the ability to include all failed screenshots to be sent to testrail, instead of just the last one.
3. Fixed an issue that prevents failed screenshots from being uploaded at all.

I could use some help verifying all my changes work @boxblinkracer :)

just to let you know,...it could be that i rename the config keys in JSON...pretty long names, maybe i can come up with sth shorter,
