Add an option to spawn command in a shell

[seanpoulter]

Summary
This adds the option to spawn a Jest command in a shell from jest-editor-support. On Windows, using the shell option will handle adding the .cmd and .bat extensions to the pathToJest.

The issue is discussed in jest-community/vscode-jest#98.

Test plan
Unit tests have been added.

Not sure what's up with Circle CI. The "restoring cache" step is failing:

Unarchiving cache...
tar: root/jest/node_modules: Cannot mkdir: Permission denied
tar: root/jest/node_modules/.bin: Cannot mkdir: Permission denied
tar: root/jest/node_modules/.bin/JSONStream: Cannot open: Permission denied

I've tried amending the last commit, popping a commit off the branch and re-committing fresh, and I'm not having any luck. 😭

Shouldn't index.d.ts contain an updated Options definition?

[seanpoulter]

@stephtr, you're right. These two type definitions have diverged.
