I improved applet part: it got configuration (enable/disable
dictionaries, reorder them).

The qstardict engine expects dict list to be embedded into source, e.g.:
en-ru-bars,wordnet:test
where 'test' is the word queried.
if just 'test' is specifyed then all dictionaries are used in random order.

KDE now is in feature freeze, so I'm releasing my plasmoid separately
(and besides, there is some more work to be done on both applet and
dataengine side).

Whole qstardict may be moved to KDE SVN (kdeutils module?) for KDE 4.3.

As for web plugin - yes, it needs reworking. But main plugins are
stardict itself and multitran -- for local dictionaries.
for example, this is very handy on a notebook, which doesn't have
permanent internet connection or the link is very expensive.
