Toaster documentation update

Hi,

This patchset contains changes to Toaster documentation caused by the switch to Python 3:
- usage of pip3 --user in favor of virtualenv
- usage of mod_wsgi for python 3
- changed list of required packages

There are also changes unrelated to Python 3:
- added instructions for production setup on OpenSUSE Leap 42.1
- changed instructions for apache as it's upgraded to 2.4 in the latest distro versions
- used isolated setup for runbuilds using screen/tmux terminal multiplexers

The setup was tested mainly on OpenSUSE leap 42.1 host and partly in docker containers for Ubuntu 16.04 LTS and Fedora 24.

Note: While working on this and looking at new ways of delivering software opened by Docker I tend to think that we should start building preconfigured docker containers for Toaster instead of maintaining setup and deployment instructions.

The following changes since commit d9c6c6e1a241913fae26bf97030965ef89b91b0f:

toaster: remove SSTATE_MIRRORS from projectconf (2016-06-24 16:05:19 +0100)
