ede/evoke/EvokeService.cpp
Sanel Zukan 2ea73b6996 Merged changed pkg.m4 from edelib
ede-panel has alternative way of calling ede-about dialog

Dumped SettingsApplicator.* code from evoke. They are replaced with ede-settings-apply script
which should call all programs that needs to apply stored settings. This will reduce code entropy

evoke will call ede-settings-apply at the startup

ede-bell-conf modified to use "--apply" arg and to apply known settings

ede-desktop will start icon exec path via ede-launch

Fixed freebsd specific code in ede-panel's battery code
