Creates a automated report tool

This simple PHP can be loaded via browser: /system/webdriver/tests/report/index.php
And provides a report of the run tests, getting the data from:  /tests/system/webdriver/tests/logs/junit.xml

This code is a mix of code from @puneet0191 and mine. @kshitijSharma2014 feel free to improve it ^_^

Notice that: yellow lines are warnings and red ones are errors
