Get PHPUnit with composer
Don't remove original repo on install
Apache service name in config.ini.inc
Adapt runner and command to PHPUnit 3.7

Since TestSuite has no getGroupDetails() method, our workaround
consists in subclassing TestSuite to gain visibility on the
protected fields that stores groups.

We also commented out a line calling unexisting method
setRunTestInSeparateProcess(). We should check if this code
is needed when dealing with complex suites.
