tribune 6.x-1.13

Mostly bugfixes for this version:

• Fixed a PostgreSQL warning - #779764: upgrading Tribune from tribune 6.x-1.11 to 6.x-1.12;
• Fixed the 'size' attribute of the block textfield - #779764: upgrading Tribune from tribune 6.x-1.11 to 6.x-1.12;
• Fixed the textfield turning white while checking new posts;
• Better detection of nonstandard useragents.

A few new features:

• The « active users » block now automatically refreshes periodically - #598114: Show active users;
• The url filter now has an option (enabled by default) for opening links in new pages - #643614: URL _blank?.

And a somewhat important change:

• Anonymous users used to be represented by their useragent (eg. FF3.6Win) unless you installed the "no_useragents" filter. Now the default behaviour is to display them as "Anonymous" unless you disable this in the filter settings. This will only affect new tribunes: if you want to enable it on an already existing installation, after updating enable the "no_useragents" filter in the filter settings.
