test: install test dependencies in top-level

Since top-level dependencies are found by the node applications in
test/, its not necessary to use a script to (multiply) install every
dependency of the test apps - the dependencies can just be dev
dependencies of this package. This simplifies the build scripts, and
speeds up the installation process.
gitignore: sort, and remove irrelevant entries
chdir: tracks PWD like shell `cd` builtin does
restart: follow symlinks when restarting cluster

Rename slr script to slr.js

It will still be called `slr` and `sl-run` during npm install, but
appending the .js suffix makes the file format clear to dev tools.

Rename slr script to slr.js

metrics: fix wrong url part being used for host

The host returned by url.parse() is the NAME:PORT, if you want just
the NAME, it is the hostname.
