adding tsconfigs to test folders to reduce jest type errors in vscode

[ATorrise]

What It Does
Configures typescript test files to include jest type information, reducing the amount of distracting, not-real-yet-still-highlighted-as-such errors when working in test files

How to Test
Pull branch and start opening up some test files, making sure there are no errors like:

Cannot find name 'describe'. Do you need to install type definitions for a test runner? Try `npm i --save-dev @types/jest` or `npm i --save-dev @types/mocha`.ts(2582)

Additional Comments
Each tsconfig file includes the following section:

"include": [
  "../**/*.ts"
]

This provides any .ts file in any directory within the parent directory information on jest types
