Do not constrain ruid to html5.
settings.chunks might not exist in predictRuntime(), so check for it's presense first.
Tests, Uploader: Switch to fake runtime - 'test'.
When destroying the uploader, purge the queue as well and unset private variables.

To avoid potential memory leaks.
Unset controls in case of initialization errors of some kind.
Update moxiecode/moxie@06f556855ccf777775e4aea69d6df612207f38ba.
Bring back the 'runtime' property.

Turned out to be highly requested one.
UI: Bring back the refresh() method.

Might get handy, when UI Widget is placed within the popup, that is
constantly hidden and shown again - without calling this method after
each show operation, dialog trigger might get displaced and
disfunctional.
