Extracted the Piwik\IP class into a standalone Network component
Added tests for deprecated methods in Piwik\IP class

refs #6429 new AMI, will delete the old one now! On start we move mysql data dir to RAM now to speed up system tests from 16min to under 8 minutes and integration tests from 3 minutes to under 1:30min. I wanted to do this in the AMI but it seems not to persist it so we have to do it when the instances launches.
Fix one test as the error message now starts with "Error in Piwik"
Fixed tests:run command description
Removed useless test
Inversed PHPUnit assertEquals to match (expected, actual)
Make sure setup-fixture command does not overwrite config on normal UI tests run.
Fix regression in error page that occurs when custom logo URLs cannot be accessed (due to DB connect error).
Better error message when connection to AWS failed
