Is it possible to set the -P options when running scalatest

[juliangp]

When running scalatest it is possible to set the thread count when running in parallel mode:

• https://www.scalatest.org/user_guide/using_the_runner

argument	description	example
-P[S][integer thread count]	specifies a parallel run, with optional suite sorting and thread count (Note: only one -P allowed)	-P, -PS, -PS8, or -P8

@juliangp Unfortunately I don't see that option from the source, will be a nice enhancement though, including the sorted 'S' support. I'll see if I can help with this.

@cheeseng thanks - I can provide a PR as well if needed - to keep backward compatibility you will probably need to keep parallel as boolean and add a new option that overrides parallel if set?

@juliangp Thanks for offering to help, I have submitted the following PR:

#97

and yes I maintained parallel and added two new suiteSorting and threadCount, to make it backward compatible.
