This patch moves the title_format information from windows to containers.
Furthermore, it allows correctly setting it on window-less containers and
displays the title accordingly for split containers.
We now also dump and read title_format in GET_TREE / during restarts.
fixes #2120
and the following placeholders which will be replaced:
+%title+::
- The X11 window title (_NET_WM_NAME or WM_NAME as fallback).
+ For normal windows, this is the X11 window title (_NET_WM_NAME or WM_NAME
+ as fallback). When used on containers without a window (e.g., a split
+ container inside a tabbed/stacked layout), this will be the tree
+ representation of the container (e.g., "H[xterm xterm]").
+%class+::
The X11 window class (second part of WM_CLASS). This corresponds to the
+class+ criterion, see <<command_criteria>>.
