Feature #117 - Add refresh on file change

[bcox280]

Related Issue/Keyword: Closes #117 Closes #84

Description: The functionality supplied in this branch adds a package that allows the electron app to reload when a change is detected. This branch changes the 'npm start' script to also compile the typescript and run the electron app. Now, when a change occurs in the TS files, the electron app will reload and display the new changes. There is also another package added that allows for easier batch running of npm scripts.

Tests: Not applicable in this case, as the only part of the application that changed were the npm scripts and a small change to the electron start-up.

When testing this branch, you will need to:

• Delete node modules
• run npm install
• run npm start
• Make a noticeable change in the codebase (add a random visible word etc.)
• Check that the electron app updates and displays the new updates

It would be nice to have this tested on multiple OS's, since the package used does some file look up stuff which may not be consistent over multiple OS's
