revert: update to work with Karma 0.11

This reverts commit b744d6f2d01eb37b7160f5e82885e597132a167a.
chore: release v0.1.2
refactor: use onExit instaed of explicit emitter
feat: add a default config and normalize outputFile path

We used to do this in Karma's config, but it really belongs here.
feat: log where the coverage reports are generated
test: fix the unit tests
fix: update to work with Karma 0.11

Since Karma executes immediately, we don't have all the browsers in advance, the reporter has to listen on browser_start instead.

This re-introduces b744d6f2d01eb37b7160f5e82885e597132a167a but in a back-compatible way.
feat: support coverage for coffee script
chore: update readme with info about teamcity reporter
feat: update instanbul
chore: release v0.1.3
feat: Update ibrik version to 1.0.1

Fixed `make` dependency in ibrik for non-Unix environment.

Closes #39
chore: release v0.1.4
