Fixed in dev. branch: svn://svn.zabbix.com/branches/dev/ZBX-2506

(1) Some problems with the doubleOrder() function:
1. we cannot define a class inside a function;
2. everywhere we define the sort order using the ZBX_SORT_UP and ZBX_SORT_DOWN constant, let's do the same here;
3. the sort class has no reason to use static properties and methods.

<Toms> RESOLVED in r28394. It turned out that we have a multisorting class, and ... it uses static methods

<pavels> It uses static method because the class was never meant to be instantiated, while your's was used as an object. CLOSED.

(2) The sort order has to be fixed in the dashboard filter as well.

<Toms> RESOLVED in r28394

<pavels> CLOSED.

I've improved the comment a bit in r28398, so we don't forget what exactly is wrong =)

TESTED.

Fixed in 2.1.0 r28483 and 2.0.2rc1 r28482

regression : extra colon is prefixed in dashboard filter for host groups in a non-dm setup

..F....... ZBX-2506 fixed ordering for dashboard filter; fixed multisort function

dev branch: svn://svn.zabbix.com/branches/dev/ZBX-2506

(1) The node name should be separated from the group name by a colon, but it shouldn't appear in a plain setup.

<Vedmak> RESOLVED

<pavels> CLOSED.

TESTED.

Fixed in pre-2.0.2rc1 r28956, and 2.1.0rc1 r28957

another regression : dashboard widgets are not sorted by host group anymore, added as ZBX-5396
