Don't set cmd[0] to the window ID

Ahoy,

the attached patch fixes a tiny issue with tabbed. When running it
without a command and having it run spawn(), it tried to execute its
window ID as a command. While most people probably don't have
executables called 341123 or the like in their path, I think that is not
exactly intended. The following patch fixes that:

Subject: [PATCH] Don't set cmd[0] to the window ID

Starting tabbed without a command sets cmd[0] to the window ID of
tabbed. This leads to funky errors such as "execvp: <ID> failed: no such
file or directory" when running spawn().

Fixed obscure miscalculation when a client is closed.

This crops up whenever you just switched from tab # N+1 to tab # N
and close current tab. unmanage() first decreases lastsel
(so it becomes N) then erroneously tests it against sel and focuses first tab
instead. One can see that focus() would never set lastsel == sel,
so I took liberty to fix this annoying behaviour which happens to frequently
with newposition = 0 and npisrelative = True settings.

select or open new tab with Ctrl-T

The default config will display all open tabs in dmenu. You can either select
one of them, or if you enter a string, that does not start with „0x“, tabbed
will open a new tab and run the command specified at tabbed-startup but append
the entered string to the command first.

With
tabbed -r 2 surf -e ''
you can hit Ctrl-T and either select an already opened tab or enter an URL,
which will be opened in a new tab with surf.
