New sub-class structure and better Laravel version support

This is a major structural change where instead of subclassing from Laravel directly we created a copied version of the Laravel classes we were depending on and sub-classed off them. This way we can better support the newer version of Laravel.

Major changes

1. Created a copied version of Laravel dependant classes under src/Laravel.
2. Changed the way the work exited removing the use of the Stop exception.
3. Dropped support for old Laravel and PHP versions.
4. Added support for latest Laravel versions.

Add Laravel 5.6 to CI & removed PHP 5.6 from CI

Minor release that focused on testing and CI.

1. Added an multi job unit test
2. Added Larvel 5.6 using PHP 7.3 to CI
3. Removed PHP5.6 version tests from CI

Simplify Testing with LaraAppSpawn and Improve Stop exception handling

• Simplify Testing with LaraAppSpawn
• Improve Stop batch exception handling

Travis CI Testing
