More options for datagard

New, rewritten datagard, which is responsible to correctly install Midgard has now more usable options. Basically it upports different setup types and different setup actions. Or combinations.

First you can start quick setup mode:

datagard -t q

It installs Midgard and doesn't ask you any questions, taking good default values for everything.

You can also set some key in configuration file:

datagard -t config -c midgard -a config-set loglevel message

Use 'config' setup type, take named 'midgard' as configuration and set 'message' as 'loglevel' key.

Create new sitegroup or new virtual host ( with default wizard setup type ) :

datagard -a sitegroup
datagard -a vhost

In latter case you are also asked for sitegroup, so if you want to create both, select this option. An interesting fact is that datagard, when creating new host will ask you if you want to create host for MidCOM3. When you say 'yes', your MidCOM3 has no page elements and empty content for page.
