added generic client support (thanks Stephen)
XKill if windows won't close, cleanups.
removing XSetInputFocus() calls to be ICCCM compliant again. Thanks to Thomas Adam
Some cleanups
I will recheck if these are really cleanups tomorrow. Too much coffein be sure right now.
focus fix for openbox (and maybe a few others)
tabbed remembers last viewed tab; open new tabs focused/unfocused can be configured now.
removing autoclose when last client exits.
closing tab with middlemouse, circling tabs with mousewheel.
sorting functions alphabeticly
Handling maprequest. that means tabbed works for xterm.
works better now with windowmanager who use mapping/unmapping
fixing unexpected closing of tabbed when unmapping it.
formating xembed messages with spaces instead of tabs
fixing focus/activation of embedded clients.
code cleaning, windows are properly closed on exit; if last client quits, exit
