Renamed lots of things, like ScreenSaverThread to ScreenSaverRunner, refactored code, etc. Much cleaner interfaces and code. * Fixed a couple of bugs and in the add-on handling, especially some settings related bugs (ie. testing a screen saver will now use its latest settings, etc.). * Correctly implemented DPMS support in ScreenSaverPrefs and the ScreenSaver preferences application - screen_blanker still ignores them, though. * It's not yet font sensitive either. * Changed the input_server add-on to not switch to the screen blanker immediately when it's in the "blank corner" - doesn't seem to work yet, though (only tested under Qemu). * Correctly implemented the "preview" function (before, a screen saver would never know it rendered a preview). * Evaluates the return value of BScreenSaver::StartSaver(). * The screen saver thread is no longer killed without notice - it's now always shut down properly. * Made the code more robust against failure. * Introduced some new bugs as well (the screen saver list view doesn't jump to the selection anymore, for some reason), those will be fixed later (as the remaining issues). * Probably some more I forgot about. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17731 a95241bf-73f2-0310-859d-f6bbb57e9c96
