Preprocessor failure should cancel (not even start) the execution

[hlship]

When I have errors in my CoffeeScript, I see two problems:

1. The compilation error is reported without a line number, making it hard to chase down the problem.

INFO [watcher]: Changed file "/Users/hlship/workspaces/annadale/nexus/client/novate-console/src/test/unit/api-services-spec.coffee".
ERROR [preprocess.coffee]: unexpected INDENT
  at /Users/hlship/workspaces/annadale/nexus/client/novate-console/src/test/unit/api-services-spec.coffee
Chrome 26.0 (Mac) LOG: '{\n  "a": 1,\n  "b": 2\n}'
Chrome 26.0 (Mac): Executed 5 of 5 SUCCESS (0.457 secs / 0.068 secs)

2. The test runner reports success for the tests that did run; however, the test run should be a failure if any sources could not be compiled. In the above, the 5 tests that ran passed, but there were another 7 that never executed due to the compilation error.

This is in Karma 0.8.5.

Totally. I created a separate issue for the coffee-preprocessor plugin (to report line numbers).

Any failure during preprocessing should fail the whole run. Probably even not run.

Just updated the issue title.

I fixed this in the coffee preprocessor, but it will be available with Karma 0.12, as this is a breaking change (it's in https://github.com/karma-runner/karma-coffee-preprocessor/tree/preprocessor-error-karma-0.11.14).
