Author-names(#81): unit tests setup

Installed php-pecl-xcebug in vagrant chef recipe as it is needed by phpunit to calculate test coverage.
Set up the creation of a test database in gigadb chef recipe, so that unit tests can run without disrupting manual and automated user testing by wiping out the development database.
Created a db_test.json config for the test database.
Moidified Yii test config to use the test database.
Run the test coverage for the gigadb-website codebase and generate a comprehensive html report.
