[Clam-devel] Versioned networks

[David García Garzón]

In order to make upgrades in the proper way, i just have added a 'clamVersion' 
attribute to the network xml that holds the major and minor version ("1.3" 
for 1.3.1~svn2434). This way the upgrade scripts can take it into account.

For the first release, networks without the version will be silently loaded 
and when saving the version will be added. On future versions i plan to 
complaint (suggesting to apply an upgrade script), and eventually upgrading 
automatically.

Sorry for the reds while i was commiting that.

David.
