Seperate react components into single files

[azerella]

Currently our react components are all bundled into the single file, this PR separates each component into a seperate file.

The seperate files are concatenated together in the lib/react/react.js and then bundled like normal.

• [x] Add jsdoc to react files: #725

NOTES:

• The form component requires other component libraries when running webpack, during the build process, when said libs haven't built yet, an error occurs. To mitigate this we need to remove build:react from the main build script in form. This is issue is also referenced in #730
