Patch by plfiorini: Integration of InfoPopper as a system service. See ticket
#1245. There are some TODOs outlined in the ticket, but they will be much easier to review as individual patches against trunk, versus as a new version of the huge patch. I've messed a lot with src/servers/notification/NotificationsView.cpp in order to resolve a crash I was getting when testing this thing (rewrote line wrapping). I've also replaced the icons with the one that zuMi did long ago. Thanks, plfiorini, for working on this code as much as you did! git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@36949 a95241bf-73f2-0310-859d-f6bbb57e9c96
