There's a bunch of generated files that webpack relies on to work, and Karma works off webpack. To make both happy we've added
a new `build:genfiles` script which takes care of this for us. We also have to install and build our other layers to get the
same effect (like generating the react-sdk's component index, while we still have one).
This commit also fixes all the imports in the tests because they were just wrong. They should have been caught in the ES6ification
earlier, but were missed.
If you try to clone a repo that doesn't exist via `https`, `git` will prompt for
auth credentials and hang forever. Using `git` avoids this and fails immediately
instead, which is what we want for a missing repo.

Currently, people with push access to the main Riot repos can push matching
branch names to Riot and the SDKs, and CI will test all the branches together.
This change allows contributors to access the same ability when submitting
several matching PRs from their fork of each repo.

Most `npm` operations are replaced with `yarn`, which generally has better
behavior. However, steps like publish that write to the NPM registry are left to
`npm`, which currently handles these tasks best.
Attempt both the PR author's branch and the PR's target branch. This resolves
issues on experimental where we need matrix-react-sdk to also be experimental.
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.
* tell git to checkout the right branch, rather than cloning and then changing.
* clone with depth 1 under travis, to save time.
* less pushd/popd, which print out confusing text - use `cd` in a subshell
instead. (and just avoid it where possible).
* add some markers to the output to let travis roll it up.
