Remove scattered calls to bar_update when switching workspaces and
cycling layouts, which are preceded by a focus function call. They
already are (as they should be) responsible for doing that.
Like the other focusing functions, make focus_prev call kill_refs before
trying to focus on a new window. This way, the current window references
are cleared like it should be when the very last window is destroyed.
Otherwise, the status-bar output will contain (while its alarm does not
expire) the class hint of the to be removed window.
The update functions already check if the window related enabled options
are set. Just call it directly, instead. As a consequence, the wrapper
function can now be deleted.
The window's class hint is already retrieved by the manage_window
function, which is called when a new application is spawned. Therefore,
use it when displaying the application's class and name, instead of
fetching them again with XGetClassHint(3).
Besides, its error checking was incorrect, since it also returns zero on
error.
Add new keybindings for workspaces 11 through 22.
Defaults for ws_n and mvws_n are NOD+(F1-F12) and MOD+Shift+(F1-F12),
respectively.
Add a new configuration option 'workspace_limit' to make it possible for
the user to adjust the number of available workspaces. Default is 10.
