Introduction of new CI system

[Ben Cooksley]

Next week we will be introducing the new Continuous Integration system.
It can currently be found at https://build-sandbox.kde.org/

Prior to the switch over taking place, all developers are *strongly*
encouraged to check the status of their builds and tests. You will
also need to check the dependencies which have been installed.

This can be done by reviewing the build logs and other information
displayed by Jenkins for your project.

If your project is in Extragear and you have not previously requested
for your coverage to be continued then you will likely need to request
this.

Additionally, if you have previously requested for email alerts to be
provided, these will need to be re-requested.

The new system among other things has the option to provide both
FreeBSD and Windows builds. If you are interested in this for your
application, please file a Sysadmin request.

Note that in the case of Windows builds you'll need to provide
assistance in getting builds functional for everything above
Frameworks to your application in the event it depends on other KDE
software.

In regards to Qt 4 support, this has been discontinued. Only KF5 / Qt
5 builds are supported from this point onward.

Regards,
Ben
