+Rename some classes
+-------------------
+
+Attention to not break apps like Anjuta and Builder, so renaming classes should
+either be done in a backward-compatible way (deprecate the old classes, provide
+the new ones in parallel and implement the old classes by using the new ones),
+or it should be done for the next major version of the libdevhelp, with the
+different major versions being parallel-installable (which means moving the
+libdevhelp to its own git repo).

+- DhSidebar -> DhSidePanel. A "bar" in GNOME is more for horizontal things,
+  like GtkInfoBar.
+- DhKeywordModel -> DhSearchModel ?
