This reverts commit 3b1e58a8bb62046e37e920723a627ce023bd842c.

disable redirects which is not very broken at the moment and not possible to separate from aliases at this point.

Move recreation of config files to the http parent class, because the web cluster class wasnt calling it.

got the order of the test the right way the first time. now also test for an additional error. escape some backticks.

update the centos help a bit. no longer specify -h when creating the aegir_root account, so that the root@localhost account is used instead.

Rewrite install docs so that the aegir_root user is created by install.sh.txt, and we test for mysql and the hostnames before running script.

Removed the nginx-debian install.sh.txt because it conflicts with the 'one true way' of installing aegir. It can be hosted elsewhere and
linked to in docs.

Added (in docs) all-in-one install script for Aegir with Nginx on Debian Lenny minimal OS vanilla install (fix).
