Spork support added

Created by: Andrew8xx8

I can no longer pay attention to the fact that the test running in a project takes a lot of time. It is awful, especially if you work everything out on the virtual machine.

I think that I would be supported by a lot of people that the spork implementation will cut the time required to load the environment.

I cannot provide the test performance for all the tests because I do not have enough patience to wait until all the tests pass on my machine.
