[PATCH] list_padding command

[Florian Bruhin <me _at_ the _minus_ compiler _dot_ org>]

1) be bored in train at 6 in the morning
2) implement list_padding for hlwm
3) ???
4) PROFIT!

Sorry if you need to copypaste the patch, don't have an MTA set up, so
no idea how to use git send-email correcly.

If anything is wrong or can be improved, let me know.

Sample output:

$ herbstclient list_padding                          
0: 24 0 0 0
1: 23 42 23 42
