This reverts commit 8e274dd6.

Fix site search reports are not displayed in scheduled reports

refs #6511 fixed some tests which shows it seems to work now. I presume the expected results are correct but I do not know. Also updated another test where someone committed his path from his local server

refs #6511 this should fix sitesearch reports are not available in scheduled report as there was no siteid set

Extracted the IP class into a standalone Network component

Fix regression in error page that occurs when custom logo URLs cannot be accessed (due to DB connect error).

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.

Speed up unit tests

refs #6533 move travis yml generator to testrunner plugin. This way the command will be only available via git in the future as we hopefully remove TestRunner plugin from latest.zip
