Make Remote Coverage data available to IDE

Story:

In order to view the collected coverage data
As a Tester
I want to get the feedback in the channel I'm currently viewing

Scenario:

Given that I run the test suite with Maven
When the Jacoco Maven Report plugin is active
Then the Jacoco Extension should write out the collected data to disk

Given that I run the test suite in Eclipse IDE
When the ElcEmma Jacoco IDE Plugin is active
Then the Jacoco Extension should report the data to the plugin

Rationale:

The Jacoco Extension has no idea if it's running in Maven or IDE and will only dump the data to the configured output directory. This works fine for Maven as the communication between the Jacoco Runner and Jacoco Reporter is file based. But this does not seem to be the case when executed from IDE. The Jacoco Extension should detect where it's running from and provide both with the data in the way they want.

The collected remote coverage data should be viewable in IDE, merged with the locally collected coverage data, when calling "Coverage As -> Junit".
