improve and speedup circle ci setup

[DominikGuzei]

Fixes the CircleCi tests and improves performance by caching all important parts of the application and test dependencies.

The chimp script is moved outside of the package.json file because i ran into several issues with chimp and Node.js 0.10.x that Meteor is using. So the problem is that if you run Node via meteor npm run you are forced to the Meteor node version. if you run it from outside you can have Node.js 5+ installed globally and basically run Meteor and chimp with different versions.

Here are the related Github issues and discussions:
xolvio/chimp#204
xolvio/chimp#201

Bottom line: Meteor really has to upgrade to use up-to-date Node.js versions soon. Until then, we cannot use the package.json with chimp.

This also removes the unit and app-tests from the CircleCi run since they fail for me. Probably i should also fix these but i do not have enough time at the moment 😢

Let's do it!

Thanks @DominikGuzei !

This line is causing errors for me when I run ./tests/acceptance_run or ./tests/acceptance_watch. If I comment it out, the tests run fine.

Any ideas?

When you run the tests locally on your machine, you have to start the "normal" app first – this is done because otherwise the testing environment would override your local DB everytime. What we do here is this: the normal app is started and then the testing app uses the special Meteor MongoDB server to setup a chimp_db on the same mongo instance. This simplifies the setup because you do not need to have a standalone mongo installed and setup correctly locally.

So do this:
meteor

wait until the app runs, then in a different terminal:
./tests/acceptance_run or ./tests/acceptance_watch

Looking at the output of CircleCI, it looks like this isn't running any tests. Am I missing something?

@noahsw the problem of no running CI tests is fixed in #171 😉 thanks for the feedback.
