Reduce the number of terminals required to build riot-web to 1

Browse source 
A step towards a real solution for https://github.com/vector-im/riot-web/issues/7305

This approach makes use of `npm link` to remove the use of symlinks in the build process. The build process has also been altered to invoke the build process of each underlying SDK (react, js). This means that one can now `npm link` and `npm start` and have a working environment. 

At the same time, parallelshell was dropped due to lack of maintenance from the maintainer.

When you make changes to `matrix-react-sdk` or `matrix-js-sdk`, you will need
to run `npm run build` in the relevant directory. You can do this automatically
by instead running `npm start` in the directory, to start a development builder
which will watch for changes to the files and rebuild automatically.
When you make changes to `matrix-react-sdk` or `matrix-js-sdk` they should be
automatically picked up by webpack and built.
If you add or remove any components from the Riot skin, you will need to rebuild
the skin's index by running, `npm run reskindex`.
