[ANNOUNCE] qgit new "smart browsing" feature

I've pushed a patch series to git://git.kernel.org/pub/scm/qgit/qgit4.git that implement a new and much improved way to browse a repo.

What -------

- Possibility to switch from revision message to diff content in
bottom left pane of main view

- Possibility to jump to next/previous revision with link labels at
the pane corners

- Optional use of mouse wheel to perform all of the above actions

How ------

In the bottom left pane two labels have been added. Both contain some links, a default one (big) and a secondary one (small), mouse wheel action performs the default link action when scrolled out, above or below the content view.

Links could be switched right clicking on them by the means of a popup context menu.

Finally in Edit->settings menu a check box called 'Show always revision message as first' has been added. When checked (suggested), on jumping to a new revision the log message is shown first, regardless of the previous pane content.

Notes --------

Care has been taken to allow the wheel browsing experience to be as natural as possible, in particular a way to avoid to switch when user just wants to scroll has been implemented. Also, getting a responsive scroll and switch command avoiding false positives was not immediate.

I have found, to my surprise, that more the natural behaviour was obtained more the code amount was big. At the end a quite not trivial class has been added just to let the user browsing without thinking on how to do it.

Hope you enjoy it. Of course feedback is, a always, welcomed.
