* Status Bar now available for Scan Popup window as well.
* Fixed #13: Eliminated modal box when sound is not available:
Instead of modal dialog box we now show the status bar message,
with error icon, thus making it visible but not disruptive.
* Proper handling of status bar images.
* Styling of the status bar in both modes
(in Mani Window and in Popup Window).
Now when a user activates an article (by clicking on it, or by using Alt-Up/Down shortcuts),
corresponding dictionary in the "found in dictionaries" pane is selected.
See Issue #22.
P.S. Lingvo behaves in the same way too.
* Small pop-up window at the bottom of the main winodw instead
of traditional status bar, that consumes lots of space.
* API, similar to standard Qt's status bar.
* The status bar hides itself after specified amount of time.
* Clicking on the status bar also hides it.
* Properly behavies on resizes/moves/focus/etc.
* Tested on Linux and Windows.
This is a standard behavior for any history-enabled app
(like web browser). When there is no previous or next item
in the history, the appropriate button on the toolbar
is disabled.
It is a separate detacheable pane, which could also be enabled/disabled,
it tracks the current tab's contains, and lists those dictionaries that
contributed their content to the current translation.
Clicking on dictionary name jumps to the appropriate article from
this dictionary, which improves the navigation flow.
The Dictionaries Pane:
* Shows both dictionaries' names and icons.
* Does not consume resources when hidden.
* Properly styled.
* Properly handles app-wide shortcuts
(Esc, Ctrl-L, Alt-D, Enter, Alt-Up/Down).
