Navigating the TOC, viewing a full screen image, browsing
reading stats... would call paintTo() on ReaderUI (so, asking
the engine to render the page) or FileManager (so, rendering cover
images) even though their content is hidden.
Widgets registering to UIManager have to explicitely states
they cover the full screen (UIManager can't know, parts of their
dimen may be transparent, e.g. if it is a CenterContainer).
crengine may now give us multiple authors (if multiple <dc:creator>
in epub metadata) separated by \n.
Deal with that where needed.
Limit the number of authors displayed in coverbrowser views.
Bumped base/crengine: multiple <dc:creator> + fix mobi images order
Bumped base: util.runInSubProcess(): give child its own process group
Closes: #3236 and #3235
Details:
> Also, when looking in days, we see info how many hours we read. It would be great if we could tap a day, it opens info on book(s) we read that day with info pertaining to that day, and if we tap on book, we receive book info for that book.
> Statistics plugin is really great, I started to look in my reading statistics now much more, but all the time I can go only in one way. And I need to exit at lowest level of info. It would be great if I can use statistics plugin like part of menu, to go up and down within statistics data and exit at my wish, not when I have to.
Also added:
* new statistics book by week
* new statistics book by month
* last year by week now we can see days in selected week
