ShowImage: Multipage images displayed in sequence.

* The correct page is displayed.
* Next/Previous/First/Last page are enabled and disable
as Next/Previous File.
* Add in the status bar current page/ total page.
* Fixes #11959.

Tracker, Deskbar, ShowImage: move public commands

... to tracker_private.h so they may be used by external apps
such as Deskbar and ShowImage. Remove PublicCommands.h

Coding style changes, no functional change.
Hope all's OK, Filter.h is still mostly untouched as it's quite messy with
many exessive commenting.

* adjusted to earlier move of NaturalCompare() to libshared.a
(wasn't broken, it's just a bit clearer now).

Resolve TODO: Use Tracker's NaturalCompare in ImageFileNavigator in order
to preserve a consistent display order regardless of whether Tracker scripting
or the internal navigator is being used to iterate through images.

Fix some style violations and silliness (returning something in a void method.)


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@40181 a95241bf-73f2-0310-859d-f6bbb57e9c96

Add an auto-adjusting image navigator which can switch to a folder navigator
when the Tracker window is closed. Tested with normal navigation and
slideshows.

Axel's excellent navigation classes code made this pretty easy.

CID 5772: Delete the unneeded (and leaked) ref on the loop end case.

* The FolderNavigator now allows you to open a folder directly as well.
* The TrackerNavigator should do the same in the future, though.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39427 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Implemented preloading of the images around he current one; always two in the
direction of the current navigation, and one in the opposite direction.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39377 a95241bf-73f2-0310-859d-f6bbb57e9c96

* The ImageFileNavigator is now only for navigation, it doesn't load any images
anymore.
* Moved the new ImageCache into its own source file.
* The cache is now used within ShowImage. There is no read-ahead caching being
done yet, though, but you can quickly return to previous images, and you can
also skip images faster than before.
* Improved separation between the ShowImageStatusView and the rest;
ShowImageWindow no longer has a getter for the image view.
* The status view is now using the private BDirMenu which implements enhancement
ticket #6778.
* Made a few more methods private/protected in ShowImageWindow.
* Fixed bug #6797.
* The bitmap is currently only owned by the ImageCache, but we need to have a
separate referenceable object owning it. Added a TODO comment for this.
* The ProgressWindow is currently not being used anymore, added a TODO comment
for this as well.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39364 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Work in progress on implementing asynchronous image retrieval with a
read-ahead cache. Not yet done or used.
* Added deleting images via delete key again. The only difference to before is
that it will open the previous image if the last image in a folder was
removed, and only close ShowImage if there is no image left.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39322 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Moved the Tracker navigation logic into its own class, TrackerNavigation.
* Added a new class FolderNavigation that implements the same for folders
without a Tracker window.
* ImageFileNavigator is now using either one depending on whether it got a
valid tracker messenger.
* Removed some unused/unneeded methods.
* Made entry_ref a reference at some more methods, as it's not really optional.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39292 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Completed stippi's work on the ImageFileNavigator.
* ShowImageWindow is now using such a navigator.
* Removed navigation support from ShowImageView.
* Prepared everything to support asynchronous image loading (which is not yet
implemented, though).
* Note, this commit brings some regressions I intend to fix in the next few
days, namely deleting files won't work anymore, and dropping images onto
ShowImage. There might be more I don't know about, though :-)

Part of a refactoring/rewrite I was once working on,
work in progress, don't remember how far I got. Supposed
to extract the image file and document page navigation
from ShowImageView. Not included in build. Untested.
