Display perms on mail user list

It's useful when you need to disable some accounts, or you need to look for disabled accounts

Dns delete check

Now dns zone requires domain is created on domain module (if that feature is enabled), it should be checked as mail domain and web sites are checked.

Default php handler

I added a default php handler setting for server. I want to use PHP-FPM for hostings, so I only enable PHP-FPM on client templates. However, when admin create hosting must remember to change php handler becuase default is FastCGI. With this patch, default php for default server is set.

Vhost sql fix

Fix for changing tab on site web, when logged as admin.

Hide client

When domain module is enabled in config, every module has a domain selector now, and changing domain's owner on domain list changes owner for every module. This patch removes client selector when domain module is enabled, because I don't see the point in having a client selector on mail, sites and dns, neither create nor update, because setting client to a different one than domain's owner, if that client try to edit, it will break because it's not domain's owner.

Change owner on domain module changes on mail domain, sites and dns too

It's related to #97 merge request
Instead of displaying a warning about owner must be changed on mail and domain too, change it everywhere.

I have fixed some records which were not changed owner when changing mail domain's owner or web site's owner.

If you agree, I'm thinking in disable client selector on mail, domain and dns when domain module is enabled.

Reseller quota

When a reseller has some quota established, they shouldn't be allowed to create clients without quota or assign more quota to their clients. If they are allowed (as it's done now), total quota used by their clients can be higher than reseller limit, and when reseller try to edit site or mailbox, then quota can be changed to 0.

Merge branch 'favourite_servers' of http://git.ispconfig.org/Cambra/ispconfig3 into Cambra/ispconfig3-favourite_servers

Hide used domains

Domain must be unique for mail, dns or web site, so there is no point in get used domains on domain select (with domain module enabled) and this patch get only unused domains. For subdomains it doesn't apply, so it's not used.

This patch added some code to dns module because I added domain select on merge request #105 and commit is included here because I based this branch on branch from merge request #105. I can rebase to master if you #105 is merged if it's needed.

Master Fixes

Change for vmail-uid/gid settings in subdomains and aliasdomains

- Added incremental sql query collection file to make merging easier and avoid high patch file count

Fix is reseller

reseller are now allowed to have -1 for limit_client, but I found another place where a > 0 check was used
