service_watcher() would not be drawn correctly yielding program hang since
add_fd() would not send events to fltk.
Also commented hack from Splash to keep it's window at the top of all;
now, using add_fd() evoke will get events before fltk which is what I want.
Not tested with other wm's.
Note: enabling that hack will surely crash evoke unless fl_handle() is removed
from main evoke loop.
without possible stealing from fltk. Prevous, add_handler(), would send only
unknown events for fltk which leave us without really important ones, like selection events
used by XSETTINGS manager.
Added XSETTINGS support (yet unfinished) which will make evoke as XSETTINGS manager.
session should be logged out. Previous version (althought commented) was
closing all windows (buttons and rest are counted too), not their main
window. Thanks to some old code from babaya project I found, XmuClientWindow
is what I needed, so emulation is provided to avoid linking with libXmu.
Also added some more signals to detect quitting.
Pending issue: I'm getting strange sound driver locks when X are started
via evoke. This is un-reporoduceable when evoke is started from gui console.
This still needs to be investigate.
