added parameter mail_smtpauthtype to set SMTP authentication type. 

The debug mode should not be enabled in productive environments and is also a security risk since some apps outputs unsanitized debug data to the template.

fixed an other typo.

Fixed type in line 70. Thank you for pointing me to that typo.

Added three additional mail_smtp.. parameters.
- mail_smtpdebug - enable debug messages to analyse SMTP problems.
- mail_smtptimeout - set SMTP timeout which is set to 10s by
  default and this is sometimes to short especially if a malware/
  spam scanner is used.
- mail_smtpsecure - force secure SMTP connections.

Let's remove it, it's also not secure anymore with the introduction of
our API etc...
(And doesn't work with ldap etc…)

Thanks Bart for the hint.
This also switches "==" to "<>" and not the code actually works ;-)

make it possible to manually override the hostname and protocol if the automatic detection from ownCloud fails. This can happen in reverse proxy situations or with loadbalancers setups.

Conflicts:

	config/config.sample.php

a salt is generated during setup and used to salt the user password hases in the database backend

generate a random salt during installation and store it in the config.php. use it to salt the password hashing.
