Check for production status

[flowirtz]

When deploying to github-pages, the baseurl path is broken: "/jenz" is missing.
This can be addressed by using env vars.
NG2 does not support env vars.
Therefore, a status.ts file that holds a boolean production is used.
Upon deploy, the boolean needs to be set to true.

TODO

• Check whether this is BS: Why not use an npm env var that gets set in Travis / is undefined by default?

• Use Travis to auto-deploy on push/merge/commit to master

• Repair deploy

Should be "kinda fixed" with e61d86c, but also see #18
