<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">This patch fixes multiple klipper issues:</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">* Moves filtering logic into a background task. This makes Klipper responsive while the clipboard is being filtered.
Previously, Klipper would "hang" while it was filtering the results. This was worse when there were no matches as
Klipper had to go through the entire history. THe computation is immediate on small history sets, but significant
on larger sets with larger strings in the clipboard
* Provides a progress bar at the top to indicate the filtering process.
* Simplifies the code significantly, by:
* Moving filtering in a separate class file
* Cleaning up Popup proxy to build the menu directly using a QList
* Removing the "index" magic in KlipperPopup. Now we maintain a list of history actions which can be easily cleared.
* Removed explicit deletion of the "more" submenus, as these are owned by the parent menus and should be removed
automatically
* Avoids flickering of Klipper while removing and inserting actions by forcing the height and width during the update.
* Fixes a potential memory leak. The QActions for the KlipperPopup were only removed, but never deleted. The API used
to add actions addAction(QAction*) was not taking ownership of the action. This is fixed by deleting the actions
manually when clearing.
* Fixes a performance issue during menu rendering when truncating large strings. The method call elidedText() can be
slow on large pieces of text. This is worked around by creating a much smaller string of the prefix and suffix of the
string. We use the average character width to compute the approximate amount of characters which can be displayed
and use twice as much. (this is because in corner cases, such as |||| we might end up with a string which is not
long enough).</p></pre>
