Travis: separate building from deployment.

- Added `-q` to the zip command to create the archive since Travis
  was having trouble handling its very long output (thus making
  the build fail).
- Moved the actual building of the index and the archive from
  deploy.sh to a new build.sh script.
- Added a `script` step in .travis.yml to run build.sh after npm
  test.
- Specified a clone depth of 1 in .travis.yml to make things faster
  since we don't need to do any git operation during the build.
