update configuration to allow the core/upgrade/install.php to have the
same read_timeout in nginx as it has in php execution time.
This should prevent the nginx timeout error when a upgrade takes longer
than 60 seconds (the deafult in nginx)
* adding devuan
* add devaun desc to README
make update and upgrade more noisy
correct path for devuan in pre-install
* some untested code for the source install - source installation is broken in Debian installation script and I have not debugged the problem. Focusing on the packaged version first.
Debian default back to PHP 5 to use Debian's default repository rather than the 3rd party repo. To get Debian 7 now go to debian/resources/config.php and change it to 7.
* added CentOS, Fedora, RHEL choices with minimal version check (recommited)
* fixed small typos
* added special option --use-php5-package
* parse options and export new environment variable USE_PHP5_PACKAGE
* added choice between php5* or php7.0* packages (recommited)
* fixed php*-fpm service name and php.ini file path (recommited)
* prepare socket name for nginx to work with php5-fpm or php7.0-fpm (recommited)
* added ppa:ondrej/php5-compat repo
* added dependency ppa:ondrej/php repo and package software-properties-common
* added execute permissions to ./centos/*.sh files
